Question

The electronic configuration of magnesium 2,8,2 from this the valence shell of Magnesiun is _____

Answer 1

Answer: two electrons in its valence shell.

Explanation:

The electronic configuration of magnesium is 2, 8, 2 i.e. it has two electrons in its valence shell. Hence it needs to lose electrons from its valence shell to attain a stable gas configuration. On the other hand, the electronic configuration of oxygen is 2, 6 i.e. it requires 2 electrons to complete its octet.
