1. What is the periodic table of the elements and how is it used?
The periodic table is a table that arranges all of the elements by their atomic number and similar chemical properties. It can be used to discover new elements.
2. How do molecules bond with one another?
They bond with when
3. What are electrically charged parts of an atom?
Protons carry a positive electric charge, while electrons carry a negative electric charge.
4. How has chemistry changed our world?
It revolutionized our scientific ways of thinking, and it has enabled scientists to create new elements.
5. What do you know about oxygen?
I know that
its atomic number is 8, and makes up a great part of the air we breathe. 6. Describe Joseph Priestley’s early experiments with gases. He heated mercury using a magnifying glass, and then it began to become ae metal and release a gas. 7. What chemical reactions have you observed? I have observed potassium in water and lemon juice with baking soda. 8. How did August Kekule’s discovery about carbon change the science of chemistry? He changed the science of chemistry by being able to describe how carbon combined with other molecules to create chemical compounds. 9. How can you tell which chemical elements are present in a burning substance? 10. How did Joseph Thomson discover electrons? He coordinated a series of cathode ray experiments. He put a magnet next to the cathode rays, and it bent. Since magnets only have an effect on matter, he supposed that what he discovered was radiant matter. What he saw was actually a stream of electrons. 11. Can you name some chemical compounds? Some of the chemical compounds that I know are sodium chlorine, water, and carbon dioxide. 12. What are the benefits of radioactivity? Radioactivity is used for many beneficial things such as x-rays and MRI’s 13. What would the world be like without plastics? 14. How do you think nanotechnology will change our world?
Although some of the elements have been known for thousands of years, our understanding of many elements is still young. Mendeleev’s first Periodic Table contained only 63 elements, and about that many were discovered in the following 100 years. Just like countries, emperors, philosophers, and cities, elements have histories, too.“The Disappearing spoon” by Sam Kean, is a detailed history of the elements on the Periodic Table. Kean does a important job of telling every single element’s journey throughout the history of mankind: from the earliest times, when chemistry was intermingled with alchemy, to these days of modern chemistry. For example: Thallium is considered the deadliest element, pretending to be potassium to gain entry into our cells where it then breaks amino acid bonds within proteins. The CIA once developed a plan to poison Fidel Castro by dosing his socks with thallium-tainted
When designing my periodic table, I probably looked up a million websites. I used Wikipedia, horses.animal-world.com, and horses.petbreeds.com. I used the petbreeds website for my information, the animal-world website for deciding the categories, and Wikipedia for deciding which horse breeds go in which category. But those were just for my final draft. Before that, I organized in about 3-5 different ways, trying to find the most efficient way of having the most elements and have then going from left to
The best-selling novel, The Disappearing Spoon, is written by Sam Kean. The book revolves around the periodic table. It goes into such depth of the table, it is literally an adventure historically, politically, and scientifically. Not to mention, it is relevant to what has been learned this school year, which is what I’ll be talking about in this paper. The book is extremely helpful in learning the periodic table of elements, which is an imperative tool to have when studying physical science or chemistry, for example. It fills an unknown void of what the table is, solving mysteries as the chapter progresses.
Bill Nye is a key figure in the scientific community. His outreach to children and his involvement with educating the public and furthering scientific inquiry and research make him one of the most influential scientists of the 21st century. Bill Nye grew up in Washington DC, after attending Sidwell Friends School, a private school in Washington DC, Bill went to Cornell University and majored in Mathematical Engineering. Bill started his entertainment career with a show called Almost Live, a comedy show where a sketch called “Bill Nye The Science Guy” had Bill do small experiments on the show. Bill then became the main entertainer of the PBS show “Bill Nye The Science Guy”, a show aimed at preteens. The show ran from 1993 to 1999 and aired
Bill Nye the science guy was an inspiration to kids all over the world. He let the children learn in a fun, and humorous ways. In his life he was an engineer. He played as a teacher in a Disney movie. He also appears in other things such as The Climate Code on The Weather Channel, VH1 reality show, and more. HE also has his own scientific work as a scientist. Bill Nye created a show that used humor to innovate ways to overcome boredom from the kids and illuminate the world by teaching the concepts of science.
Marie Curie opened the world up to the science of radioactivity. She discovered polonium and radium, two radioactive elements, and was the first person to ever win two Nobel prizes and in two different subject areas. To the modern world, her discovery of radium was significantly and forever changed our understanding of how matter (atoms) and energy (radiation) are related. Her efforts influenced and expanded theories dealing with fundamental science and brought in a new era of medical research and treatment.
Marie Curie’s discovery of radium transformed science, medicine and roles of women throughout history. She was inspired by science and wanted to learn and teach. Her perseverance led to the most influential discoveries of history. Everyday life would be entirely different without her discoveries and impact on women. “Marie Curie was a woman of firsts. She was the first woman to win a Nobel Prize, the first person to win two of them, and the first of only two people to win a Nobel Prize in two different fields. She coined the term ‘radioactivity’, discovered two elements, and became the first female professor at the University of Paris” (Gaylord csmointer.com).
The Periodic Table is based around the Atomic Theory. Firstly people believed that everything was made up the four elements Earth, Fire, Wind, and Water. This theory evolved into everything being made up of atoms. Breakthroughs throughout history such as the discoveries of the nucleus, protons, neutrons and electrons have pushed this theory forward to where it is today.
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.
All elements fit into little families or groups of other elements with similar properties. The whole periodic table is an arrangement of the elements. They are arranged by their atomic numbers so that the elements with relatable properties present in the same vertical column or group.
Now that experimentation began to be based on the scientific method, works were being published like Boyle’s, and key characteristics of alchemy were beginning to become more advanced, alchemy was now turning into the modern science, which people today now know as modern chemistry. All of the search for new compounds and elements as well as their use in medicine, industry, and more were beginning to falter from the ideas of the original concept of alchemy, thus, generating a new domain. As research began to stray from the magical and spiritual beliefs of alchemy, chemistry began to become more prominent and rise from the “ashes” of its
The 20th century was a time of great advancements in the field of technology. Men walked on the moon, polio was cured, and penicillin was discovered. Yet in our timeline of events one scientific development changed everything. The theory that not only could atoms be split to form massive amounts of energy, but that it could be utilized in a chain reaction to create a massive burst of energy.
In chemistry, metals compose a great number of the periodic table elements. Each metal has its own characteristic mass,
Antoine Laurent Lavoisier is considered to be the father of modern-day chemistry (Balchin 36). He had an unbelievable impact on the way the world views chemistry today. From identifying elements to discovering the importance of the role of combustion, he played an essential part in the world’s scientific ideas and inventions. He was so influential that he is said to have an equal if not greater impact in chemistry as Newton did in physics (Tiner 90). He used the initial ideas of Joseph Priestley, Henry Cavendish, and Karl Scheele, and worked to prove them and make them more official (Tiner 90). Because of these accomplishments, he is considered one of France’s and the world’s most outstanding scientists (Tiner 91). Antoine Laurent Lavoisier was one of the world’s most influential scientists and people of all time because he was a leading figure in the 18th century chemical revolution, he developed a theory on the chemical reactivity of oxygen, and he discovered the Law of Conservation of Mass.
Scientists from earlier times helped influence the discoveries that lead to the development of atomic energy. In the late 1800’s, Dalton created the Atomic Theory which explains atoms, elements and compounds (Henderson 1). This was important to the study of and understanding of atoms to future scientists. The Atomic Theory was a list of scientific laws regarding atoms and their potential abilities. Roentagen, used Dalton’s findings and discovered x-rays which could pass through solid objects (Henderson 1). Although he did not discover radiation from the x-rays, he did help lay the foundations for electromagnetic waves. Shortly after Roentagen’s findings, J.J. Thompson discovered the electron which was responsible for defining the atom’s characteristics (Henderson 2). The electron helped scientists uncover why an atom responds to reactions the way it does and how it received its “personality”. Dalton’s, Roentagen’s and Thompson’s findings helped guide other scientists to discovering the uses of atomic energy and reactions. Such applications were discovered in the early 1900’s by using Einstein’s equation, which stated that if a chain reaction occurred, cheap, reliable energy could b...
