Commonly (93%) to rarely (9%) recognised as a
metalloid: B, C, Al, Si, Ge, As, Se, Sb, Te, Po, At
Very rarely (1–5%): H, Be, P, S, Ga, Sn, I, Pb, Bi, Fl, Uup, Lv, Uus
Sporadically: N, Zn, Rn
Metal–nonmetal dividing line: between H and Li, Be and B, Al and Si, Ge and As, Sb and Te, Po and At, and Uus and Uuo
Periodic table extract showing groups 1–2 and 12–18, and a dividing line between metals and nonmetals. Percentages are median appearance frequencies in the list of metalloid lists. Sporadically recognised elements show that the metalloid net is sometimes cast very widely; although they do not appear in the list of metalloid lists, isolated references to their designation as metalloids can be found in the literature (as cited in this article).
