Matter is made of molecules and atoms. An atom is made of a nucleus and electrons. The nucleus contains positively charged protons and neutrons, collectively called nucleons. Nuclear forces operating between different nucleons are responsible for the structure of the nucleus. Electromagnetic forces operate between a pair of electrons and between an electron and the nucleus.These forces are responsible for the structure of an atom. The forces between different atoms are responsible for the structure of a molecule and the forces between the molcules are responsible for the structure of the material as seen by us.
