Question

Which element is likely to have a high thermal conductivity? antimony carbon chlorine sodium

Answer 1

The element which is likely to have a high thermal conductivity among given options is sodium.

What is thermal conductivity?

Thermal conductivity of any substance is define as the capability of the substance to carry heat or transfer of heat.

As we know that metals are the good conductors of heat and non-metals are bad conductors, so we exclude carbon, antimony and chlorine atom from this group as they are non-metals. And sodium atom has the thermal capability.

Hence option (4) is correct.
