Rutherford modal of an atom is also called as nuclear modal.He did alpha particles scattering experiment.he took gold foil at the centre and placed a detector and passed a source of alpha particles,this experiment is arranged in a vaccum chamber.Approximately,rutherford passed 2000 alpha particles through gold foil but only deflected back.This states that J.J.Thomsons modal of an atom is wrong.Based on the above observations Rutherford gave his modal of an atom.
i.The positively charged particles[protons] are present inside a nucleus.
ii.The mass of electron is 1836 times smaller than the nucleus.
Bohr's model of an atom is also called as planetary modal.He said that all electrons move in descret orbitals or shells.Each shell has certain energy.One electron must gain or lose energy to move from one orbital to another.The shells are named as K,L,M,N............... or 1,2,3,4..............
