Isabel Harmon · Answer 1

They are salts, ionic compounds

Explanation:

To know if they are covalent or ionic we need to check their difference in electronegativity. As an example mgcl2, mg has electronegativity of 1.2 and cl 3 so 3-1.2=1.8 which is bigger than 1.7 means it's ionic therefore they are salts

Robert Gaines · Answer 2

They are salts and are all ionic compounds because in the formula one of the element has to have a positive and the other a negative charge.
