Question

write postulates of Bohr's model of atom​

Answer 1

Answer:

THE MAIN POSTULATES OF BOHR'S ATOMIC THEORY ARE: 1. The electrons revolving around the nucleus are confined to certain fixed orbits called shells or energy levels ,each of which is associated with a fixed amount of energy. ... While it is revolving around the nucleus in an orbit, an electron neither loses not gains energy

Answer 2

Answer:

Postulates of Bohr’s Model of an Atom

In an atom, electrons (negatively charged) revolve around the positively charged nucleus in a definite circular path called orbits or shells.

Each orbit or shell has a fixed energy and these circular orbits are known as orbital shells.

The energy levels are represented by an integer (n=1, 2, 3…) known as the quantum number. This range of quantum number starts from nucleus side with n=1 having the lowest energy level. The orbits n=1, 2, 3, 4… are assigned as K, L, M, N…. shells and when an electron attains the lowest energy level, it is said to be in the ground state.

The electrons in an atom move from a lower energy level to a higher energy level by gaining the required energy and an electron moves from a higher energy level to lower energy level by losing energy.
