Question

Complete the following statements

A magnesium atom changes to a magnesium ion by losing

Answer 1

Conversion of magnesium to magnesium ion:

• Magnesium is an alkaline earth metal and magnesium is electropositive in nature.
• The electronic configuration of magnesium(12): 2, 8, 2
• So, magnesium loses two electrons to attain an inert gas configuration and form a magnesium ion.

$\underset{\mathrm{Magnesium}}{\mathrm{Mg}}\to \underset{\mathrm{Magnesium}\mathrm{ion}}{{\mathrm{Mg}}^{2+}}+\underset{\mathrm{Electrons}}{2{\mathrm{e}}^{-}}$

Thus, A magnesium atom changes to a magnesium ion by losing 2 electrons.
