Everything contains atoms. Atoms are the basic units of matter and the defining structure of elements. Atoms are made up of three differently charged particles: positively charged protons, neutral neutrons and negatively charged electrons. Protons and neutrons are heavier than electrons and reside in the centre of the atom, called the nucleus.
