Electrons in Bohr's model of the atom
Electrons with different energy levels orbit in the different shells of the atom. The electrons located in the outer shell are called valence electrons, they have the most energy and are the ones who participate most in bonding.
An essential point of Bohr's theory of the structure of the hydrogen atom was that only particular orbits with specific orbital energies are allowed. Another essential point was that energy is only absorbed or radiated by electronic transitions between these orbits.
He described the atom as a sea of positive charge sprinkled with electrons
electrons are negatively charged sub atomic particles which surround the nucleus and never leave their orbit unless and until they are excited by a photon(packet of light)

The Bohr Model.
Neils Bohr assumed that electrons follow circular orbits in his model of the hydrogen atom. However, this was later proven to be incorrect, as electrons travel as waves and are not restricted to two-dimensional motion. They occupy three-dimensional space and do not have circular orbits.
In this model, the electrons move or orbit around the protons that are at the center of the atom. Electrons move around the nucleus, which contains the proton, in orbits that have a definite size and energy.
The Bohr model addressed the problem of decaying orbits of the electrons, which was a problem with the Rutherford planetary model. If electrons are located in discrete energy levels, their orbits do not decay, and the atom does not collapse in on itself.
In this model, the electrons move or orbit around the protons that are at the center of the atom. Electrons move around the nucleus, which contains the proton, in orbits that have a definite size and energy.
Electrons were placed on different orbits around the atomic nucleus.
