Answer 1

• Mg has the smaller atomic size when we eliminate it's Valence shell electrons.
• Na is more electropositive because it Valence shell is 1. The time require to remove is less compared to magnesium.
• Na belongs to 1st group and Mg belongs to second group.

Answer 2

a) Magnesium will have smaller atomic size when we eliminate it's Valence shell electrons

b) Sodium bcoz it Valence shell is 1 the. time require to remove is less compared to magnesium
