Answer:

#"Elemental chlorine, "Cl_2# should be a gas at room temperature and pressure.

Explanation:

The metling point of elemental chlorine, #Cl_2#, is #-101.5# #""^@C#; its boiling point is #-34.0# #""^@C#. Clearly an ambient pressure of #1# #atm# is specified.

The halogen group is one of the few (the only?) groups to exhibit gaseous, liquid, and solid elements at room temperature and pressure. What is the state of fluorine at room temperature and pressure; of bromine; of iodine?
