# What would a Bohr Model for magnesium look like?

Magnesium has $12$ protons and $12$ electrons.
The first electron shell of a Bohr model holds $2$ electrons.
The second holds $8$.
So far, $10$ of magnesium's $12$ electrons have been used, so only $2$ remain.
The remaining $2$ are placed in the third electron shell, which is full when it holds $8$ electrons.
