MCQ

For an element with atomic number 19, the 19th electron will occupy:

A
L-shell
B
M-shell
C
N-shell
D
K-shell

✓

Answer

M-shell

Explanation:

Atomic number = 19

Electrons per shell ⟶ 2, 8, 9

Maximum Electrons in K = 2

Maximum Electrons in L = 8

Maximum Electrons in M = 18

∴ 19th electron will occupy M−shell.
