Bhors's theory of atom

1.	Bhors's theory of atom
Answer» $\huge{\textbf{\underline{\underline{Bohr's\;atomic\;theory}}}}$ An atom consists of a nucleus at the center at the center and electrons are REVOLVE around the nucleus in a definite CIRCULAR PATH known as orbit. Each orbit will have definite amount of energy, therefore these levels are also known as stationary states. As long as the electron revolve in the particular orbit it doesn't loss or gain the energy. The angular momentum of the electron should be equal to integral multiple of $\frac{h}{2 \pi}$ . If an electron JUMPS lower energy to higher level, it absorbs the energy, similarly when the electron jumps from higher energy level to lower energy level,it emits the energy. Energy released or absorbed is equal to different in the energy or 2 orbit and it is equal to frequency of the radiation. $\Delta E = h \nu \\ E_2 - E_1 = \Delta E$ With the HELP of these postulates Bhor was able to derive the energy and radius of the orbit of hydrogen atom. $\gamma _n = {n}^{2} a_o \: \: (hydrogen \: atom)$ _________________________________________

$\huge{\textbf{\underline{\underline{Bohr's\;atomic\;theory}}}}$

An atom consists of a nucleus at the center at the center and electrons are REVOLVE around the nucleus in a definite CIRCULAR PATH known as orbit.
Each orbit will have definite amount of energy, therefore these levels are also known as stationary states.
As long as the electron revolve in the particular orbit it doesn't loss or gain the energy.
The angular momentum of the electron should be equal to integral multiple of $\frac{h}{2 \pi}$ .
If an electron JUMPS lower energy to higher level, it absorbs the energy, similarly when the electron jumps from higher energy level to lower energy level,it emits the energy.
Energy released or absorbed is equal to different in the energy or 2 orbit and it is equal to frequency of the radiation.
$\Delta E = h \nu \\ E_2 - E_1 = \Delta E$
With the HELP of these postulates Bhor was able to derive the energy and radius of the orbit of hydrogen atom.
$\gamma _n = {n}^{2} a_o \: \: (hydrogen \: atom)$
