What is Bohr's atomic model?

Answer 1

Bohr developed an atomic model with shells.

Answer 2

1. Electrons in atoms orbit the nucleus.
2. The electrons can only orbit stably, without radiating, in certain orbits (called by Bohr the "stationary orbits") at a certain discrete set of distances from the nucleus. These orbits are associated with definite energies and are also called energy shells or energy level. In these orbits, the electron's acceleration does not result in radiation and energy loss as required by classical electromagnetics.
3. Electrons can only gain and lose energy by jumping from one allowed orbit to another, absorbing or emitting electromagnetic radiation with a frequency ν determined by the energy difference of the levels according to the Planck relation:

   where h is Planck constant. The frequency of the radiation emitted at an orbit of period T is as it would be in classical mechanics; it is the reciprocal of the classical orbit period:

   The significance of the Bohr model is that the laws of classical mechanics apply to the motion of the electron about the nucleus only when restricted by a quantum rule. Although rule 3 is not completely well defined for small orbits, because the emission process involves two orbits with two different periods, Bohr could determine the energy spacing between levels using rule 3 and come to an exactly correct quantum rule: the angular momentum Lis restricted to be an integer multiple of a fixed unit:

Answer 3

The Bohr model depicts the atom as a positive charged nucleus that travel in circular motions around the nucleus. The structure is similar to that of the solar system.

Answer 4

Bohr theory states that the electrons of an element are in orbitals of specific energy levels, additionally electrons cannot be between two energy levels.

Answer 5

The electrons are in a permanent movement around the atomic nucleus, placed on stable orbits.

Answer 6

a model with valence electrons!!!!!
