Chemistry has been the way of life for millions of years! It helps us develop new concepts of thinking and finding solutions to our problems. Did you know that fire was the first chemical reaction humans learned to use and control? (worldbook.com) Chemistry has helped our world come up with new, advanced technology to benefit us all. Chemistry played a role in developing the periodic table, x-rays, and the telescope.
Primarily, the Periodic Table of Elements was primarily thought to be developed by Dmitri Mendeleev. However, “Antoine Lavoisier first established the modern concept of the element in the late 1700s” (worldbook). Mendeleev published his version of the periodic table in 1869. Also, many scientists before Mendeleev tried grouping elements together that had similar characteristics between each other. For example, a German chemist grouped similar elements into groups of three. On the other hand, Mendeleev grouped elements by mass and properties. Later a chemist, by the name of Henry Moseley, said that elements should be grouped by their atomic number instead. As we all know, the atomic mass goes higher with the atomic number. Quantum mechanics affected the shape of the periodic table. The final changes of the periodic table were the elements we see that branch off. These elements are called the transuranium elements. I think without the development of the periodic table we may not have different types of medicines, or maybe just generic products to help us along the way of life. For example, humans need Zinc. A doctor can simply tell a person how much Zinc he/she needs or a simple nutrition label can tell how much of the element is in the product. With the development of the periodic table, it gave scientists l...

...ywhere and be used for entertainment/hobby purposes. A parent can easily get his/her child excited for looking at the glowing stars at night. Training a child when he is young so that he can be wise when he grows old is a great proverb for situations as these. This means that if you encourage a child to try out science at a young age will help him succeed later in life.
In conclusion the history of chemistry has helped in the development of the periodic table, the x-ray machine, and simple telescopes. The cool thing about all that is that each of these discoveries are still around today and they just keep getting better. Each discovery helps improver every living creature’s life. Chemistry is life, and without chemistry there is no life. This is a very powerful statement, and I believe it holds to be true. Chemistry is found in pretty much every aspect of life.
In life and society as most of you know, chemistry is involved in everything in this entire world including; animals, plants, and even food! Although most people don’t like chemistry due to all the equations and “Stoichiometry”, it plays a significant role in everyday life. Thanks to many scientists in the past, we can now use the knowledge of their theories and postulates to find new technology and other scientific advancements to help the evolvement of many organisms in this world.
The History of the Periodic Table of Elements Dmitri Mendeleev and the early Periodic Table Dmitri Mendeleev was born in Tobolsk, Siberia; on February 7, 1834 .He was the youngest of 14 children born to Maria Dmitrievna Korniliev and Ivan Pavlovitch Mendeleev. His father was director of the local gymnasium. Maria Korniliev's family settled in Tobolsk in the early 1700's and introduced paper- and glass-making to Siberia. Unfortunately, Ivan died when Dmitri was quite young, leaving his wife to support the large family. The death hit them hard economically especially for a large family, which meant that Maria had no other choice but to find work. Maria's family owned a glass factory and they allowed her to take over managing the company so she could support the family. Dmitri, being the youngest, appears to have been his mother's favorite child and was provided as many opportunities as she could afford. From his early years, she began to save money for Dmitri to attend the university.
Chemists are the specialists in chemistry, that interact with chemical properties, and reactions. The earth is made up of different gases. Some of this gases are needed for life in the planet but other gases can be harmful to the living. Gas’s use in regular quantities are favorable to the earth. The world started to become more advance and had to use more of this gases to produce everyday objects and inventions by men. Little did we knew this chemicals we going to affect us in our life. Chemist Jose Mario Molina actually discovered that chlorofluorocarbons were affecting the ozone layer.
In chemistry, we calculate and measure substance to use them in all kind of substance and form every day. It is everywhere in our lives. We use it in all we do, such as cooking cleaning, eating, even in our work force and home. The texts states: (quote) that fuel in our cars with oxygen to make the car move and run, when we cook our food or bleach our hair, chemical reactions take place. (Timberlake, K. C., 01/2014, pg. 211).
What is chemistry? According to the American Chemical Society, chemistry can be described as “the study of matter and the changes it can undergo.” This science has been improved by many amazing scientists, and, because of them, our world have never been more advanced. Rosalind Franklin was one of those scientists, and she most definitely contributed to the science of chemistry.
Chemistry is a branch of natural science that deals principally with the properties of substances, the changes they undergo, and the natural laws that describe these changes. (University of Idaho, 2014) Molecules, as small as they seem, is in the food that we eat and present in our daily lives. Today, scientists would likely know about the history of chemistry but not how chemistry has impacted history. Many would not wonder if these molecules go beyond the chemistry concepts that they have learned. For example, would the world have been different if piperine (molecule) present in pepper had not led to the discovery of the United States? The interesting fact is that molecules have and will continue to shape the world today. In this book, the authors explain in detail how 17 specific molecules had a significant impact on the history of the world. On a whole, this book is very intriguing and very suitable for chemistry lovers as well as the general public.
Chemistry is a unique thing to learn and do. Even though you have to be cautious and use exact measurements for different substances it is still fun. You can mix different substances and elements together to make a new mixture. Trial and error is often a big factor in chemistry due to the measurements needed. Failure is in chemistry a lot, but when you succeed you feel like you have learned something new.
What the periodic table tells us? Why its discovery had taken up more than 50 years? Why is Mendeleev considered to be the ‘father’ of the Periodic Table? The periodic table is one of the most noticeable icons in chemistry. This table shows the organization of the elements in horizontal rows, called periods, and in vertical columns, called groups. It is an arrangement according to the increase of their atomic number in each element, which is equal with the number of the protons in the nucleus, and also based on similar chemical behavior and physical characteristics. Although more than 80 scientists tried to organize the elements systematically, the Russian professor of chemistry, Dmitri Ivanovich Mendeleev was the first person who successfully
I feel personally that the discovery of the atom was an important discovery for the world. With the discovery we are now able to answer questions we never even thought to ask. We are also answering questions some people asked long ago. We can now use our vast knowledge of the atom to measure the stars and be able to tell you what the stars are made of. The atomic discovery also helped us find our periodic table of elements. The periodic table of elements is a huge scientific chart that shows important facts with the help of its formation. There was a lot of constant scientific research that went into making the periodic table of elements and what it is today.
Today the Periodic table is used all around the world as a reference in chemistry. It arranges all of the known elements in a special way which help us in many ways in chemistry. This essay will be about the history of the development of the periodic table and how and where it affects us today today to help scientific research.
...ree careers make sure that every day activities do not lead to the degradation of the environment. For these reasons, it is clear that chemistry is beneficial to the way of mankind.
Chemistry is the most fascinating science to me. Chemistry applies to all things in the universe; living or non-living. Everything is made of elements which are made up of atoms of a certain atomic number. Thereafter I took AP Chemistry, I knew I had to choose a career in the field of chemistry. I understand and enjoy learning about chemistry. Chemistry is important, interesting, and ever expanding. Therefore, I must pursue a career in Chemistry.
From the unit of chemistry in grade ten science, the students have learned many things from different types of elements in the chart all the way to how each element impacts the daily life each student or even adult lives in. Some of the things I as a student have learned include how to draw the different elements in a bohr rutherford diagram, balancing chemical equations, types of chemical reactions, and even information about the different types of acids and bases. Although there were many other things in the unit, these four definately helped me learn about chemistry in a more in-depth way, as well as teaching me something very new since these were some things a few of the students had never done in the previous years. Learning this in the classroom has really opened my eyes to the world in which we live in today, many times I leave the house on a cold day and as I look upon the cold water becoming ice or even the snow falling down, I know how it is happening, why it is happening, and I can even picture the molecules solidifying as we had seen in class with many different diagrams.
The periodic table was first discovered about 200 years ago. In 1869, a Russian chemist named Dmitri Mendeleev separately published results which supported the ideas of periodicity suggested a few years earlier by John Newlands. Mendeleev arranged the 60 or so elements known to him in order of increasing relative atomic mass. His first table showed that elements with similar properties fall in the same vertical column. These columns of similar elements are called groups and the horizontal rows of elements are called periods. Mendeleev's table had gaps, he left gaps in his table in order that similar elements would fall in the same vertical column. He suggested that in due course, elements would be discovered to fill these gaps, and he also
Throughout my school career I have always loved chemistry. In Chemistry there was always a sense that there was more, there was always something new and exciting to be discovered and theories to be proven (or even disproven). Chemistry was the main subject with a real practical aspect to it during school and it is this, along with my genuine fascination with the subject, which fuels my desire to study it further.
