Question

Name a metal and a non-metal which exists as a liquid at room temperature.

Answer 1

Metals:

1. The elements that gain a positive charge due to their ability to form positive ions by losing or donating electrons.
2. Example: Iron($\mathrm{Fe}$), Copper($\mathrm{Cu}$), Silver($\mathrm{Ag}$), Mercury($\mathrm{Hg}$) etc.
3. Usually metals are solid at room temperature.
4. The metal, which is liquid at room temperature, is Mercury($\mathrm{Hg}$).

Non-metals:

1. The elements form negative ions by gaining or accepting electrons.
2. Example: Nitrogen($\mathrm{N}$), Oxygen($\mathrm{O}$), Fluorine($\mathrm{F}$) etc.
3. Most of the non-metals are gases and some are solids.
4. The only non-metal, which is liquid at room temperature, is Bromine($\mathrm{Br}$).
