The electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. The ordering of the electrons in the ground state of multielectron atoms, starts with the lowest energy state (ground state) and moves progressively from there up the energy scale until each of the atom’s electrons has been assigned a unique set of quantum numbers.

Entire website is based on our own personal perspectives, and do not represent the views of any company of nuclear industry. It is by mass the most common element on Earth, forming much of Earth’s outer and inner core. The commercial use of beryllium requires the use of appropriate dust control equipment and industrial controls at all times because of the toxicity of inhaled beryllium-containing dusts that can cause a chronic life-threatening allergic disease in some people called berylliosis.
