                              Atom An atom is the smallest particle of an element which can take part in a chemical reaction.                 Components of an atom An atom has two main parts: I. The nucleus (made of proton and neutron) II. The shells (electrons) which surrounds the nucleus at definite distance.                   Structure of an atom                    Sub-particles of an atom An atom is made up of three sub-particles namely: I. Proton II. Electron III. Neutron  Proton and neutron are the nuclear particles found in the nucleus, while the electrons are in constant and continuous motion in the shells at various energy levels around the nucleus.         Characteristics of the sub-particles  ...
