What Is Electron Configuration?

Also known as electronic configuration. A sign of the electronic state of an atom, ion, or molecule. According to the orbital approximation of quantum mechanics, each electron in an atom, ion or molecule is considered to be in a certain spin and orbital state. The total spin and orbit of all electrons in the system constitutes the electronic configuration of the entire system.

The electronic state of a molecular system can also be represented by the total number of single electron orbitals in which all electrons are located. Heteronuclear
