The post-transition metals, also known as the poor metals, is a group of metals on the periodic table. They are to the right of the transition metals. 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. They include lead, tin and other softer metals.
