Question

explain borh's model of an atom and it's limitations​

Answer 1

Answer:

The Bohr Model is very limited in terms of size. Poor spectral predictions are obtained when larger atoms are in question. It cannot predict the relative intensities of spectral lines. It does not explain the Zeeman Effect, when the spectral line is split into several components in the presence of a magnetic field.

Answer 2

Bohr's Atomic Model

1) Bohr told that the electrons move around the nucleus in fixed paths called Orbitals kr Shells.

2) Each orbital or shell is associated with a definite amount of energy.

3) As long as the electrons revolve in a particular orbit,the electron neither gains nor loses energy.Therefore these orbitals are called Stationary orbitals and the electrons are said to be in Stationary energy states.

4) An electron jumps from a lower to higher energy level, by absorbing energy but when it jumps from higher to lower energy level,it loses energy

Limitations:

1) It could not explain the spectral series for the multi electron atoms

2) He failed to explain the Zeeman effect and Stark effect
