Question

the electronic configuration of magnesium is 2,8,2. From this it is understood that the valence shell of magnesium is _____​

Answer 1

Answer:

M shell

Explanation:

Answer 2

Answer:

M shell

Explanation:

Electronic configuration = K, L, M, N, O

The last shell of the atoms shows its valency

Here K=2,L=8 and M=2

Here M is the last shell of the electronic configuration of magnesium.

Hence M is the valance shell of Magnesium.
