A
Very high ionisation energy and weak metallicbond
B
Low ionisation potential
C
High atomic weight
D
High vapour pressure
Answer
Very high ionisation energy and weak metallicbond
Explanation
Solution
Mercury is the only metal which is liquid at 0∘C. It is due to very high ionisation energy which results in weak metallic bonding.
