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.

The group 13 elements include post-transition metals.

The p-block metals are the metals in groups 13‒16 of the periodic table. Usually, this includes aluminium, gallium, indium and thallium; tin and lead; and bismuth. The epithet “post-transition” in reference to aluminium is a misnomer, and aluminium normally has no d electrons unlike all other p-block metals.

Other elements sometimes included are the group 11 metals copper, silver and gold (which are usually considered to be transition metals); the group 12 metals zinc, cadmium and mercury (which are otherwise considered to be transition metals); and aluminium, germanium, arsenic, selenium, antimony, tellurium, and polonium …

Gold Can’t Be Destroyed, only Dissolved It will not corrode, rust or tarnish, and fire cannot destroy it. The only way gold could truly be destroyed is through nuclear reactions. However, there does exist a way to dissolve gold using “Aqua Regia,” which is a mix of hydrochloric and nitric acids.

The metal is abundant enough to create coins but rare enough so that not everyone can produce them. Gold doesn’t corrode, providing a sustainable store of value, and humans are physically and emotionally drawn to it. Societies and economies have placed value on gold, thus perpetuating its worth.
