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. They include lead, tin and other softer metals.
These metallic elements include aluminium, gallium, indium, tin, thallium, lead, and bismuth.Most are soft or brittle, with poor mechanical strength, and have melting points lower than the transition metals.
