metals. Group 3A to 4A except Boron, Carbon, Nitrogen, oxygen, silicon,
phosphorus, sulfur, germanium, astatine, selenium, antimony, tellurium, polonium
are basic metal. Carbon, nitrogen, oxygen, phosphorus, sulfur and selenium are
nonmetals. Boron, silicon, germanium, astatine, antimony, tellurium and polonium
are metalloids. Groups 7A are halogens. Groups 8A are noble gases. The lower
part of the periodic table are lanthanides and actinides.</span>
