Question

How will the compound MgCl2 formed their elements??​

Answer 1

Answer:

mg _ magnesium

cl _ chlorine

MgCl2 is an electrovalent compound

Explanation:

Mg atomic no. = 12

electronic configuration = 2,8,2

needs to give 2e^- to become stable

valence e^- = 2

Cl atomic no. = 17

electronic configuration = 2,8,7

needs to take 1e^- to become stable

valence e^- = 1

Mg will need 2 Cl atoms to become stable

hence they both form ionic or electrovalent compound to achieve there stable octets.

hence they form MgCl2
