HEY GUY HERE IS YOUR ANS FIRST U FOLLOW ME 》》♥️♥️
The BOHR MODEL has an atomic consisting of a small positively charged nucleus orbited by negatively charged electron. here's a closer look at the bohr model which is sometimes called the RUTHERFORD BOHR MODEL.
niels bohr proposed the bohr model of the atom in 1915. the model number of atom is based on the quantum mechanics. the model contains some errors, but it is important because it describes most of the accepted features of atomic theory without all the levels of the modern vision. unlike earlier model bohr model explain the RYDBERG formula for the special emission lines of atomic hydrogen.
main points of bohr model》》
1. electrons Orbits the nucleus in Orbit that have a set size and energy.
2. the energy of the orbit is related to its size .the lowest energy is found in the smallest Orbit.
3. radiations is observed or emitted when an electron move from one Orbit to another.
problems of bohr model》》
1. it violates the Heisenberg Uncertainty Principle because its consider electron to have both are known radius and Orbit.
2. the bohr model provides an incorrect value for the ground state orbital angular momentum.
3. It make poor predictions regarding the specta of large atoms.
4. it does not predict the relative intensities of spectral lines.
5. it does not explain the zeeman effect.
hope its help you

Neils Bohr gave atomic model in 1913.The main points of this model are:
1) An atom consists of a central positive part called the nucleus which contains all the protons and neutrons.
2) Electrons which are present outside the nucleus revolve around the nucleus in definite circular paths called orbits or shells.
3) Each orbit has a fixed energy and the orbitals are represented by the symbols K, L,M, N etc or by the numbers 1,2,3 …
4) Each orbit can accommodate not more than a fixed number of electrons.
5) Electrons moving in the same orbit donot lose or gain energy.
6) Electrons lose energy on jumping from a higher orbit to lower one and vice-versa.
