Question

The electronic configuration of four atoms are given in brackets:

L ($1s^{2}2s^{2}2p^{1}$) M $(1s^{2}2s^{2}2p^{5})$

Q $(1s^{2}2p^{2}2p^{6}3s^{1});$ R $(1s^{2}2s^{2}2p^{2})$

The element that would most readily form a diatomic molecule is.

• A. Q
• B. M
• C. R
• D. L

Answer 1

Answer: (B)

M

Answer 2

: By sharing of 1 electron each both the atoms of M will get a completed octet.
