What is the electron configuration of magnesium?

In order to write the Mg electron configuration we first need to know the number of electrons for the Mg atom (there are 12 electrons). When we write the configuration we'll put all 12 electrons in orbitals around the nucleus of the Magnesium atom. read more

The electron configuration for magnesium is 1s2 2s2 2p6 3s2. Electron configuration is a representation of how electrons are arranged in an atom or molecule. read more

The electron configuration of a neutral magnesium atom is: 1s2 2s2 2p6 3s2 or in shorthand [Ne] 3s2. Magnesium has 2 valence (outer-shell) electrons and will lose both to fulfill the octet rule, becoming Mg2+. read more
