Question

Important points of bohr modal

Answer 1

Electrons revolve around the nucleus in a fixed circular path termed “orbits” or “shells” or “energy level.”

The orbits are termed as “stationary orbit.”

Every circular orbit will have a certain amount of fixed energy and these circular orbits were termed orbital shells. The electrons will not radiate energy as long as they continue to revolve around the nucleus in the fixed orbital shells.

The different energy levels are denoted by integers such as n=1 or n=2 or n=3 and so on. These are called as quantum numbers. The range of quantum number may vary and begin from the lowest energy level (nucleus side n=1) to highest energy level. Learn the concept of an Atomic number here.

The different energy levels or orbits are represented in two ways such as 1, 2, 3, 4… or K, L, M, N….. shells. The lowest energy level of the electron is called the ground state. Learn the concept of Valency here in detail.

Answer 2

The energies of electrons are quantised.
The electrons can only revolve around the nucleus on an orbit called stationery orbit,which the integral multiple must be equal toh/2π.
