Post-transition metal | Chemistry | Fandom

Post-transition metal or poor metals are terms applied to the metallic elements in the p-block of the periodic table. Their melting and boiling points are generally lower than those of the transition metals and their electronegativity higher, and they are also softer. They are distinguished from the metalloids, however, by their significantly higher boiling points in the same row. This page
