Write Bohr's Model of Hydrogen atom and its limitations.

1.	Write Bohr's Model of Hydrogen atom and its limitations.
Answer» Bohr's Model of Hydrogen Atom : (1) Electrons in an atom occupy stationary orbits of fixed energy at different distances from the nucleus. (2) When an electron jumps from a lower energy state to a higher energy state it absorbs energy or emits energy when such a jump occur from a higher energy state to a lower energy state. (3) The energies of an electron in an atom can have only certain values. E₁, E₂, E₃ ...that is the energy is quantized.The states corresponding to these energies are called stationary states and the possible values of the energy are called energy levels. Limitations : Bohr's model failed to account for splitting of line spectra.

Answer»

Bohr's Model of Hydrogen Atom :

(1) Electrons in an atom occupy stationary orbits of fixed energy at different distances from the nucleus.

(2) When an electron jumps from a lower energy state to a higher energy state it absorbs energy or emits energy when such a jump occur from a higher energy state to a lower energy state.

(3) The energies of an electron in an atom can have only certain values. E₁, E₂, E₃ ...that is the energy is quantized.The states corresponding to these energies are called stationary states and the possible values of the energy are called energy levels. Limitations : Bohr's model failed to account for splitting of line spectra.
