The Periodic Table.
The Periodic Table is an arrangement of the chemical elements and is one of the most important references for anyone doing chemistry. The elements on The Periodic Table are arranged according to their atomic number and their electronic configuration. The atomic number is listed next to the chemical symbol for the element in the top left corner. The atomic number can also be known as the Proton number of an element. The electron configuration of an atom is the representation the arrangement of electrons that are distributed among the orbital shells and subshells - http://chemwiki.ucdavis.edu/Inorganic_Chemistry/Electronic_Configurations
There are two types of bonding in atoms, one is Ionic and the other is Covalent. Ionic bonding occurs when a positive ion and a negative ion are attracted and join together, thus forming an ionic compound. Sodium Chloride is an example of an ionic compound. Covalent bonding occurs when two non-metal atoms combine. This also means that they share electrons to gain a stable electronic structure.
The Periodic Table has developed and changed throughout history as scientists have continued to discover new
The different elements are assembled into different groups. I shall start with the Alkali Metals, these are all the elements in the first column, and the column is marked in yellow. The first column is also referred to as Group 1, next to it stands another column in light blue. This is Group 2 and it consists of the Earth Metals. The next group is Group 3, this is the section of the Periodic Table which is in a sort of dark blue. This particular group consists of Transition Metals and is the largest of the Groups. The next group is highlighted in a light and pale yellow, these are The Halogens. Finally, we move onto The Nobel Gases. These are in the section of the table which is a peachy orange

  • Mendeleev's First Periodic Table

    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

    An atom, by definition, is the smallest part of any substance. The atom has three main components that make it up: protons, neutrons, and electrons. Protons and neutrons are within the nucleus in the center of the atom. The electrons revolve around the nucleus in many orbitals. These orbitals consist of many different shapes, including circular, spiral, and many others.

    Covalent compounds are formed when two or more non-metals react together. The covalent compound is actually made of molecules, and the name given depends on the structure of these molecules. Prefixes, like di- for two, tri- for three, tetra- for four, and so forth, are frequently used. Thus, NO2 is nitrogen dioxide and N2O4 is dinitrogen

    In the Classifying Elements lab, the main purpose was to determine what characteristics would be used to divide the chemical elements into groups with similar properties. In order to place elements into groups two tests were held: test one was used to determine the physical properties of the substances such as being shiny or dull, and malleable or brittle. Test two was held to determine the chemical properties of the substances such as, the reaction when HCl or CuCl2 is added. After studying the two test results, it was certain that these substances could be placed in groups based upon the similar characteristics, such as physical and chemical properties.

  • Primo Levi's The Periodic Table

    Primo Levi’s The Periodic Table is an autobiographical memoir in which Mr. Levi -an esteemed chemist- uses different elements to represent separate aspects of his life. The book molds fiction and memoir which he connects all through his study of chemistry either metaphorically or literally through his study of these elements in the lab. Specific elements connect to his Childhood and young adulthood as well as through his time in the Auschwitz concentration camp. What makes the memoir extremely unique is how it uses different elements both as literal objects he used in chemistry and also the comparisons and metaphor he creates between characters and the elements he titles the chapters. The main uses of elements in The Periodic Table are; comparisons between characters, representation of his current

    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.

    And then, it uses the electrons in the outer shell to form bonding pair with another atom’s valence electrons. When every atoms’ outer shell are fill with electrons, this is the Lewis structures of the molecule. Around the 1920s, quantum mechanics was gradually developed. And Schrödinger’s equation and molecule orbital theory can give the elections’ orbitals a more mathematical description.

  • Ionic Bonding Essay

    946 Words  | 2 Pages

    Ionic bonding occurs between metals and non-metals atoms. Metals atoms have one to three outer shell electrons they will achieve a more stable electron arrangement if they lose these electrons, on the other hand, non-metals will need to gain electrons to achieve a noble gas electron structure. Potassium chloride (KCl) is an example of an ionic bonding, potassium outer shell has one electron and chlorine outer shell seven, as a result, potassium outer electron transfer to chlorine making the both elements with outer main levels full. The electron is transferred from metal to non-metal, making potassium a positively charged due to loss of one electron and chlorine negatively charged because it gains an electron. The negative and positive ions attract each other by electrostatic forces forming an ionic bond compound, a lattice. when repeated create a giant ionic lattice hard to melt. The covalent bond occurs when two non-metal atoms share the outer electron to achieve a noble gas arrangement. Atoms held together by electrostatic attraction between the nuclei and the shared electron, with just a few atoms forming a small covalent structure or with millions of atoms forming a rigid

    From these properties of bonds we will see that there are two fundamental types of bonds--covalent and ionic. Covalent bonding represents a situation of about equal sharing of the electrons between nuclei in the bond. Covalent bonds are formed between atoms of approximately equal electronegativity. Because each atom has near equal pull for the electrons in the bond, the electrons are not completely transferred from one atom to another. When the difference in electronegativity between the two atoms in a bond is large, the more electronegative atom can strip an electron off of the less electronegative one to form a negatively charged anion and a positively charged cation. The two ions are held together in an ionic bond because the oppositely charged ions attract each other as described by Coulomb's Law.

    Dalton’s atomic theory says that each element contained its own number of atoms. Each element had its own size and weight. Dalton’s idea said that all things are made of small bits of matter this bits of matter where too small to be seen even with a microscope. Scientist began to think these small bits of matter where responsible for chemical changes. They thought that when these bits of matter combined a chemical change took place. Dalton assumed that there was a special pattern in the elements and was partly responsible for the periodic table.
