Answer
Mercury and Bromine
Reason — At room temperature, most metals and non-metals are solids, but there are a few exceptions :
- Mercury (Hg) is the only metal that exists as a liquid at room temperature (around 25 °C) and it remains in liquid form because of its weak metallic bonding and low melting point (−38.83 °C).
- Bromine (Br2) is the only non-metal that is liquid at room temperature. It has a deep reddish-brown color and easily evaporates to form brown fumes.
Thus, the metal and non-metal that exist in the liquid state at room temperature are Mercury and Bromine, respectively.
