The most common element in the universe is hydrogen.
All the atoms of an element have the same number of protons in the nucleus of each atom. When the nucleus of a radioactive element such as Uranium splits into pieces, the "new" atoms formed have smaller numbers of protons in each atom.
If atoms of same element combine, we say that element is existing in its real state (or simply a molecule of that element is formed). If two atoms of different elements combine, a compound is formed.

An element is formed from atoms; atoms are formed from protons, neutrons and electrons.Protons and neutroms are formed from quarks and gluons.A molecule is formed fro atoms.
