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. In a quantum mechanical
Transuranium element found. Transuranium elements may be utilized to synthesize other super-heavy elements. Elements of the island of stability have potential important military applications, including the development of compact nuclear weapons. The potential every-day applications are vast; the element americium is utilized in devices like smoke detectors and spectrometers. Transuranium element The transuranium elements (also known as transuranic elements) are the chemical elements with atomic numbers greater than 92, which is the atomic number of uranium. All of these elements are unstable and decay radioactively into other elements. Of the elements with atomic numbers 1 to 92, most can be found in
