A mineral is a homogeneous solid that can be made of single native element or more usually a compound. It has a chemical composition of NaCl (sodium chloride) and is commonly used for table salt, hence the nickname rock salt. The reason why silicon is the most common element within the rocky planets, is because it was the most common element (next to hydrogen) in the original nebula that condensed to form the Solar System.
