    1. An atom is made up of three kinds of particles electrons, protons and neutrons.

    2. Electrons are negatively charged, protons are positively charged and neutrons are neutral, i.e, they have no electric charge.

    The number of electrons and protons are equal, so that an atom on the whole is electrically neutral.
