The periodic table is a graphic display of all the known chemical elements that have been discovered. It gives details about their atomic number and chemical symbol. The elements are grouped together according to similar properties that they possess. The table is color-coded to show different groups such as the alkali metals, the alkali earths, the halogens, and the noble gases. It is used primarily in the study of chemistry and physics as it shows how different elements will interact with one another. It is also used in fields such as geology, biology, materials science, engineering, agriculture, medicine, nutrition, environmental health, and astronomy. It was invented by Russian chemist Dmitri Mendeleev.
