Mercury is a liquid metal because

A

it has a completely filled d-orbital that causes d - d overlapping

B

it has completely filled d-orbital that prevents d-d overlapping

C

it has a completely filles s-orbital

D

it has a small atomic size

Text Solution

Verified by Experts

The correct Answer is:
B
The electronic configuration of mercury is `[Xe]4f^(10), 5d^(10), 6s^(2)`. Its d-subshell is completely filled, thus, it prevents the overlapping of d-orbitals
(d-d overlapping). Hence, it is liquid at room temperature.
