Post-transition metals are generally considered to be elements in Groups 13, 14, and 15. All of the classifications include the elements gallium, indium, tin, thallium, lead, and bismuth. However, depending on how “post-transition” is defined, this category may contain as few as six or as many as 22 elements. The post-transition metals share many similarities with the metals, including malleability, ductility, and conductivity of heat and electricity, but are usually softer and have lower melting and boiling points than the transition metals. They have poor mechanical strength, form covalent bonds, and display acid-base amphoterism.More

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
