Question

bohr modle can explain

Answer 1

Neils Bohr said that only certain special orbits called discrete orbits are present in an atom. While revolving in discrete orbits electrons do not radiate eneregy.
For understanding, consider our sun as nucleus and planets as electrons then the solar system is the sttructure of tge atom

Answer 2

Neils Bohr, a Danish physicist, in 1913 proposed model of atom which rectified the problems left by Rutherford’s Model. He proposed that

(a) Electrons revolve round the nucleus in a fixed orbit.

(b) He called these orbits as ‘stationary orbit’.

(c) Each stationary orbit is associated with fixed amount of energy, thus electrons do not radiate energy as long as they keep on revolving around the nucleus in fixed orbit.
