Element: mono di tri tetra .. hexa .. octa atomic elements
Examples He, Cl2, O3, P4, .., C6, .., S8
Elements are made up of only one kind of atoms. For example graphite and diamond are forms of the element carbon, and only contain carbon atoms.Atoms of a single element may combine as molecules, or structurally as allotropes, in a number of ways.
An atom is composed of a single central nucleus, which contains protons and neutrons, surrounded by orbiting electrons.
compounds
If you mean a substance made up of only one atom, that would be a mono-atomic element, and would be a noble gas.If you mean a substance made of only one kind of atoms, that would be an element.
If it is a pure substance, than only one! Now that pure substance may contain many different elements (as many elements can make up a single pure compound), but a pure substance means only one compound.
A substance in which all the atoms are the same is called an "element".
Isotope
A substance that is composed of only one kind of matter is called an element. The smallest particle of an element is called an atom.
