The Science of Chemistry an Introduction

Chemistry is the field of science that is the study of the interactions of atoms to form molecules and their properties. Chemistry go back to before known civilization with fire and metal work. The book of Genesis in the Bible tells us that metal work goes back to Tubal-cain who lived before the Flood. Modern Chemistry grew out of Alchemy and its search to turn metals like lead into gold and the so called elixir of life. Chemistry acquired much from Alchemy particularly its affinity research and experimentation. Once Chemistry broke from Alchemy it lead to an explosion of knowledge about the nature and structure of matter.

Chemistry starts with individual atoms of different elements such as hydrogen, carbon and oxygen. These atoms then come together to form molecules such as water which is made of one oxygen atom getting together with two hydrogen atoms, methane which is made of one carbon atom getting together with four hydrogen atoms and carbon dioxide which is made of two oxygen atoms getting together with one carbon atom. These are all different substances with different properties.

The Periodic Table is a list of the chemical elements organized by recurring properties. The information about each element included varies but often includes element’s name, atomic number, symbol, and atomic weight. It is a vary use full took in Chemistry and one the most recognizable things associated with Chemistry.

Chemical reactions are the process by which atoms come together or are rearranged to form new molecules. There are two main types of chemical reactions. Endothermic reactions which use heat energy in forming new molecules and exothermic reactions which release heat energy in forming new molecules. Exothermic reactions are some times explosive which is a common danger in Chemistry.

The two main fields of chemistry are organic chemistry and inoganic chemistry, Organic chemistry which is chemistry based on the element Carbon and may or may not involve life and inorganic chemistry which is chemistry not based on the element Carbon.

In conclusion chemistry is a major field of science and it is the most experiment based field of science. Chemistry embodies the ideal of science stated in the scientific method more than any other field of science.
