The elements shown are in the family known as the halogens. What do the atoms in this family of elements have in common? Select one:

A || They have the same number of neutrons.

B || They will form ionic bonds with water molecules.

C || They have the same number of valence electrons.

D || They will form two ionic bonds with members from the alkali metals.

Plz choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. is it possible for two different compounds to be made from the exact same two elements? why or why not? with a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?
