Halogens are the only Group on the Table for which gas, liquid, and solids exist at room temperature and pressure...….

Explanation:

And we address the normal boiling points of the dihalogens…

#F_2,# #"normal boiling point"# #=# #-188.1# #""^@C#

#Cl_2,# #"normal boiling point"# #=# #-34.0# #""^@C#

#Br_2,# #"normal boiling point"# #=# #+137.8# #""^@C#

#I_2,# #"normal boiling point"# #=# #+183.0# #""^@C#

The more electrons, the more polarizable is the dihalogen molecule, and the greater the intermolecular force, and the greater the boiling point.
