Post-transition metal

Post-transition metals are elements found on the periodic table. They are located in groups 3-12, which means they have 3-12 electrons in the outermost shell. Post-transition metals are different from other metals because they are not as good at conducting electricity and heat. They are also softer and less dense than other metals. Post-transition metals are used in many different ways, such as to make jewelry, furniture, coins, and to help build things like bridges and houses.
