Question

What phases of matter do halogens exist?

Answer 1

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.
