post-transition metal

Periodic table extract showing the location of the post-transition metals. Zn, Cd and Hg are sometimes counted as post-transition metals rather than as transition metals. The dashed line is the traditional dividing line between metals and nonmetals. The symbols for the elements commonly recognized as metalloids are in italics. The status of elements 110 to 118 has not been confirmed, though elements 113-116 are sometimes considered post-transition metals.^ Aluminium is occasionally not counted as a post-transition metal given its absence of d electrons† Polonium is sometimes instead counted as a metalloid ‡ Astatine is widely regarded as either a nonmetal or less often as a metalloid but has been predicted to be a metal

The metallic elements in the periodic table located between the transition metals to their left and the chemically weak nonmetallic metalloids to their right have received many names in the literature, such as post-transition metals, poor metals, other metals, p-block metals, basic metals, and chemically weak metals. The most common name, post-transition metals, is generally used in this article.
