Elements are composed of atoms.
All elements are composed of extremely small particles called atoms. Atoms are composed of protons, neutrons, and electrons.
Atoms
At sufficiently high temperatures and low pressures, all elements are composed of atoms. At standard temperature and pressure, some elements are composed of molecules, usually diatomic molecules, as with nitrogen, hydrogen, oxygen, and all the halogens.
All matter, such as solids, liquids and gases, is composed of atoms. Any material that is composed of only one type of atom is called a chemical element.
diamonds are composed of carbon atoms only

No. All atoms, except the most abundant isotope of hydrogen, can be divided into the subatomic particles protons, neutrons, and electrons. The most abundant hydrogen isotope does not have neutrons.
