Post-transition metal

Post-transition metals

The post-transition metals, also known as the poor metals, is a group of metals on the periodic table. the post-transition metals sit between the transition metals on their left, and the metalloids on their right. The Group 12 elements are sometimes included. Sometimes germanium and antimony are included, although they are normally considered metalloids. They normally have higher electronegativities than the transition metals. Their melting points are lower, too. They are generally softer than other metals

A material is brittle if, when subjected to stress, it fractures with little elastic deformation and without significant plastic deformation. Brittle materials absorb relatively little energy prior to fracture, even those of high strength. Breaking is often accompanied by a sharp snapping sound.
