If the valence electrons were removed, what would be the ion charge of the element? mg = a. -1 b. +1 c. -2 d. +2

The correct answer is Option D.

Explanation:

Magnesium is the 12th element of the periodic table and the valence electronic configuration for this element is:

This element will loose 2 electrons to attain stable electronic configuration.

By loosing 2 electrons, this element will attain a charge of +2 units.

The electronic configuration after loosing 2 electrons and forming ion is

Hence, the correct answer is Option D.
