Answer 1

The metal which is liquid at room temperature is 3. Mercury

• Usually, all the metal atoms readily share valence electrons with other atoms to have a strong metallic bonding between the atoms which allows them to remain in the solid-state.
• Among the following given options Gold, Aluminium and Iron are such metals.
• Exceptionally, Mercury is the metal that is liquid at room temperature because the atoms of mercury aren't able to share a proper bond with neighbouring atoms. Hence, it exists in a liquid state.
