why does calcium fluoride have a high melting point - …

Both are diatomic with simple molecular structures. Both have van Der Waals forces of attraction between molecules but since Br2 is larger than F2 so has more electrons, these forces are stronger in Br2 so the melting point is greater for Br2 than F2. (Original post by Endany keroi)
