|
Iron (Fe)
|
|
|
Aluminum (Al)
|
|
|
Chlorine (Cl)

Explanation:
Detailed explanation-1: -Hence, Chlorine is not a good conductor of heat and electricity, it is an insulator.
Detailed explanation-2: -Nonmetals are poor conductors of heat and electricity, because electrons are not free to move. Nonmetals are found to the right of the stair-step line, except for hydrogen which is in group 1. Group 18 are the noble gases, which are all nonmetals.
Detailed explanation-3: -Therefore, Chlorine is a non-metal.
Detailed explanation-4: -Among all the options, only oxygen is non-metal. Non-metals do not have enough free electrons for the flow of electricity. And hence are bad conductors of electricity.
