In it it states that an element was consisted of only one atom and all the atoms that make up the resource or element have the same mass, but the masses have a effect of the element which would change like iron and gold for the two have different masses. A compound a pure substance, to different elements bonded together to create it. Although compounds have a mixed ratio of atoms and each atom has its own characteristic weight.
