Question

mgcl2 structure shell and explanation​

Answer 1

Answer:

The atoms have become stable ions, because electronically, magnesium becomes like neon and chlorine like argon.

Mg (2.8.2) + 2Cl (2.8.7) ==> Mg2+ (2.8) 2Cl– (2.8.8)

can be summarised electronically as [2,8,2] + 2[2,8,7] ==> [2,8]2+ [2,8,8]–2  via electron transfer

so both the magnesium and chloride ions have a full outer shell of electrons like a noble gas
