Question

State three features of the nuclear model of an atom

Answer 1

1) every atom comsists of a nucleous containing the entire +ve change . The whole mass of atom is concentrated this core .
2 The size of nucleous is very small compared to the size of of the atom .
3 The atom as a whole is electrically neutral with electrons revolving around the nucleous in various orbits. The centripetal force provided us electrostatic attraction between the electron and nucleous .

Answer 2

nuclear model of atom was given by Rutherford
----------------
1)the space occupied by the nucleus is very much less than the space occupied by the whole atom

2)positive charge is concentrated at one region which is inside the nucleus and maximum of the mass is in the nucleus

3)The electrons revolve around the nucleus in well defined orbits and the electrostatic force prevents the electrons from falling into nucleus
