Element
(It IS possible to alter elements by bombarding them with sub atomic particles and attempting to either augment or spilt the nucleus. Some elements are self-altering. These are the radioactive isotopes and they can change to several different elements before reaching their end state.)

How is a substance different from an element?
There are two types of substances: elements and compunds. Elements cannot be separated into simpler substances while compunds can. Take for example iron, pure iron is made of iron atoms, and they can't be divided into simpler substances, as such, iron is an element. On the other hand, salt is a substance that CAN be separated into sodium and chloride, so salt is a compound (and since sodium and chloride can't be furtherly separated they are elements). So, an element IS a substance, but not all substances are elements.
