Question

Fluorine, chlorine and bromine, iodine from
molecular solids, yet the melting point
increase from fluorine to lodine why give reason

​

Answer 1

Explanation:

Due to increased strength of Van der Waals forces down the group, the boiling points of halogens increase. Therefore, the physical state of the elements down the group changes from gaseous fluorine to solid iodine. Therefore, they are highly reactive and can gain an electron through reaction with other elements.
