... Metalloids have properties of metals and nonmetals. The nonmetals consist of H, C, N, O, P, S, Se, the halogens (17th group: F, Cl, Br, I) and the noble gases (18th group: He, Ar, Kr, Xe Rn). The noble gases have a full stable octet, so they are unreactive. Nonmetals are very brittle and are neither ...
