A metal and a non-metal that exists in liquid state at the room temperature are respectively :

Question

Given below are two statements:
Statement (I): The 4f and 5f-series of elements are placed separately in the Periodic table to preserve the principle of classification.
Statement (II): s-block elements can be found in pure form in nature.
In the light of the above statements, choose the most appropriate answer from the options given below:

Answer 1

Step 1: State of Metals and Non-metals at Room Temperature:
Most metals are solid at room temperature, with some exceptions. Non-metals can be gases or solids, with a few existing as liquids.

Step 2: Metal in Liquid Form at Room Temperature:
The sole metal that is liquid at room temperature is Mercury (Hg). Its melting point is -38.83°C, significantly below room temperature.

Step 3: Non-metal in Liquid Form at Room Temperature:
The non-metal found in liquid form at room temperature is Bromine (Br). As a halogen, Bromine's melting point is -7.2°C and its boiling point is 58.8°C, placing it in a liquid state at room temperature.

Step 4: Conclusion:
The metal and non-metal that are liquid at room temperature are Mercury and Bromine.

A metal and a non-metal that exists in liquid state at the room temperature are respectively :
