Question

state two main pastalates cy Neil bohar model of an atom​

Answer 1

• Answer:
• 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.
• 2. 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

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. ... shells and when an electron attains the lowest energy level, it is said to be in the ground state.
