Solution

The correct option is B two
The electronic configuration of magnesium is 2, 8, 2.
The electronic configuration of chlorine is 2, 8, 7.
Therefore, magnesium atom loses two electrons to attain the electronic configuration of the nearest noble gas.
The two chlorine atoms gains one electron each to attain the stable electronic configuration of noble gas.
