Question

write all the Bhor's theory​

Answer 1

Answer:

a theory of atomic structure which the hydrogen atom( Bohr's atom) is assumed to consist proton as nucleus , with a single electron moveing ductant circular orbit in corresponding orbit

Answer 2

Bohr's atomic theory explains the stability of atom and also the hydrogen spectrum.

━━━━━━━━━━━

Postulates:

1. Electrons revolve around the nucleus in circular orbits of definite energy called "stationary states. "
2. The electron doesn't radiate energy while it's in stationary state
3. Energy is emitted or absorbed in multiples of hv when the electron transits from one orbit to another.
4. The angular momentum of electron is quantarized

━━━━━━━━━━━

Merits:

1. It can explain the satisfactorily the spectra of hydrogen atom.
2. This theory can explain the stability of atom.
3. This theory helps to calculate radius of various hydrogen and hydrogen like species.
4. Also helps to Find the energy of moving electron in an orbit.

━━━━━━━━━━━

Limitations :

1. It fails to explain line structure of spectra lines.
2. It explains the spectra of one-electron species only.
3. This theory of orbits and velocity of moving electron is in contrary to Heisenberg's uncertainty principle.
