Chemistry is the science that explores the various atomic elements and the compounds that they form when these atoms are combined.
It is a highly experimental field of study, with most of the work actively involving lab experiments.
Chemistry lab work has become an extremely practical field both in and out of the lab.
The periodic table is an essential tool for understanding and visualizing the various elements.
Each of the elements consists of varying numbers of protons in the nucleus with them being presented on the periodic table in order of their increasing number of protons.
They are placed in columns based on the number of electrons in their outer shells and thus the chemical properties of each element.
Chemistry has many applications including the production of new materials by combining various elements in novel combinations.
Other applications include testing the composition of samples of almost anything.
This makes chemistry a highly practical science because it can be used to produce and analyze many things.
Chemistry has a close relationship to physics because physics explains how chemistry works.
Chemistry, however, is a highly productive field from a practical standpoint and much of what we take for granted today would not exist without it.
