Question

Mercury is the only metal liquid at room temperature due to its:-

Options

• Very high ionisation enthalphy and weak metallic bond

• Low ionisation enthalphy

• High atomic mass

• High vapour pressure

Answer 1

Very high ionisation enthalphy and weak metallic bond

Explanation:

Because of its high ionisation energy (all tilled orbitals) and weak metallic bonding, mercury (Hg) is liquid.
