Solution

The correct option is B Chemical bonding
Emission of electron
Thomson model cannot explain alpha particle scattering and spectrum of an atom. Leonard in 1903 suggested that the atom is made up of tiny particles called electrons and similar tiny particles carrying positive charge. He could not explain why the heating of metal does not eject positively charged particle.
