    The best use of an atomic model to explain the charge of the particles in Thomson’s beams is:

    An atom’s smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove.

    Explanation:

    In Thomson’s model, an atom comprises of electrons that are surrounded by a group of positive particles to equal the electron’s negative particles, like negatively charged “plums” that are surrounded by positively charged “pudding”.

    Atoms are composed of a nucleus that consists of protons and neutrons . Electron was discovered by Sir J.J.Thomson. Atoms are neutral overall, therefore in Thomson’s ‘plum pudding model’:

    • atoms are spheres of positive charge
    • electrons are dotted around inside

    Thomson’s conclusions made him to propose the Rutherford model of the atom where the atom had a concentrated nucleus of positive charge and also large mass.
