1. Given the information in the table on the right, explain the trending the
melting points of the halogens.
As we go down the group of halogens, the London (dispersion) forces increase
because the size of the molecules and therefore polarizability increases. That means
as we go down to group, there will be more energy required to melt the compounds
i.e. the melting points will increase going down the group of halogens.
2. Ice floats on water, an important physical ch
