3. a cation is a _ charged ion formed by _ electrons.
4. an anion is a _ charged ion formed by _ electrons.
5. metals usually form ___.
6. non - metals usually form ___.
7. the cations and the anions in an ionic bond are held together with a strong force known as ___.
8. covalent compounds are ___ conductors of electricity.
9. sharing of electrons results in the formation of a ___ bond.
10. ionic compounds have ___ melting and boiling points.
11. ionic compounds usually ___ in water.
12. an ionic bond is formed between a _ and a _.
13. ionic compounds can conduct electricity when they are in ___ form.
