Explanation:
Sir J.J Thomson gave the first model of atom.
He by means of cathode-ray experiment discovered the existence of negatively charged particles in an atom which led to the discovery of electrons.
He gave the plum-pudding model of an atom in which electrons are embedded in atom-like currants.
