Period 2 element Period 2 element A period 2 element is one of the chemical elements in the second row (or period) of the periodic table of the chemical elements. The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behavior of the elements as their atomic number increases; a new row is started when chemical behavior begins to repeat, creating columns of elements with similar properties. The second period contains the elements lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon. This situation can be explained by modern theories of atomic structure.

ACS Award in Pure Chemistry award was first awarded in 1931, with Linus Pauling the inaugural recipient. It is sponsored by the Alpha Chi Sigma Fraternity and the Alpha Chi Sigma Educational Foundation.
