22.1: General Concepts- Periodic Trends and Reactions The chemistry of the third-period element in a group is most representative of the chemistry of the group because the chemistry of the second-period elements is dominated by their small radii, energetically unavailable d orbitals, and tendency to form π bonds with other atoms.

Metals crystallize in closely packed arrays that do not contain molecules or covalent bonds. Nonmetal structures contain covalent bonds, and many nonmetals consist of individual molecules. The electrons in nonmetals are localized in covalent bonds, whereas in a metal, there is delocalization of the electrons throughout the solid.

Metal oxides are usually basic. MgO (s) + H 2 O (l) ↔ Mg (OH) 2 (aq) Non- metallic oxides: Non-metallic oxides are acidic. CO 2 (g) + H 2 O (l) ↔ H 2 CO 3 (aq) Nature of metal A: Since element A forms an oxide A 2 O 3 that is acidic in nature; We know that oxides of non-metals are acidic in nature; Hence element A is a non metal
