6. Group 8A elements are noble gases.
7. Transition metals have inner orbitals being filled.
8. Metals have the described properties.
9. Non - metals have non - metallic characteristics.
10. Metalloids have both metal and non - metal characteristics.
11. The law of conservation of mass states mass is conserved.
12. Ions are atoms or groups of atoms with a charge.
13. Cations are positively charged ions.
