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.

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