The correct electron configuration for magnesium is: 1s 22s 22p 63s 3 true false

False

Explanation:

Magnesium is the element of second group and third period. The electronic configuration of magnesium is - 2, 8, 2 or

There are 2 valence electrons of magnesium.

Only the valence electrons are shown by dots in the Lewis structure.  

As, stated above, there are only two valence electrons of magnesium, so in the Lewis structure, two dots are made around the magnesium symbol.

Given that the electronic configuration is:- .

Orbital s cannot accommodate 3 electrons and also in magnesium it has . Hence, the statement is false.
