We’re gift asked to identify the correct electron configuration of a Magnesium (Mg) ion.

You are watching: What is the electron configuration of mg2+

Before we have the right to do that, we have to first write the electron construction of a neutral soil state Mg

You can determine the ground-state electron configuration of Mg by locating the place in the routine table.

Ground-state way that the facet is in its shortest energy kind (not in excited state). Neutral Mg method it has no charge, definition no electrons are eliminated or added in the atom.


You check out in the over illustration of the routine table the Mg is in Period 3, team 2A, and also s-block
