Hi Nihal,

Postulates of Rutherford’s model of an atom:

i) The mass of an atom is concentrated in a small space called the nucleus.

ii) Atoms majorly consist of positively charged particles.

iii) Negatively charged electrons revolve around atoms in circular paths called orbits at very high speed.

iv) An atom is electrically neutral i.e. has no net charge.

Thanks for asking

Good day :)
