Mercury is the only liquid metal and bromine is the only liquid non-metal.
Mercury:
- Mercury is the only metal that is a liquid at normal temperatures and pressure.
- Because of the behavior of the valence electrons, mercury has a low melting point, is an electrical and thermal conductor and doesn't form diatomic mercury molecules in the gas phase
Bromine:
- Bromine has 35 electrons and with7 electrons in its outer shell it has a valency of 1 so, is very reactive.
- But, the electrons are very spread out from the atomic nucleus, hence it behaves like a liquid.
- It is non-metallic because it is a halogen gas that is liquid at STP.
