Question

K=2, L=8, M=2, the valence shell and valence electrons are

a. M, 2
b. M, 8
c. L, 2
d. L, 8​

Answer 1

Answer:

L,2

Explanation:

Explanation:

The Atomic number of magnesium is 12. Then its electron distribution is 2,8,2.

K, L and M shells have 2, 8, 2 electrons respectively. K and L shells can accommodate a maximum of 2 and 8 electrons respectively. The valence shell has 2 electrons.
