Answer 1

QUESTION: Compare Mg[Z=12] and O[Z=8] atom on the following parameters:a)

Atomic structure (energy shells) b) Electronic configuration c)valency

ANSWER :

a) the no. of shells in Mg = 3(k,l,m)

`` `` `` `` `` O = 2 (k,l)

B) configuration of Mg = 2,8,2

" " " " " " " O = 2,6

C) valency of Mg = 2 (valence e¯ at otter shell)

valancy of O = 2 (need 2e¯to be stable)
