The Bohr Model was proposed in 1915. CITATION REQUIRED During 1913, Niels Bohr, a physicist, managed to explain the spectrum of atomic hydrogen with the help of Rutherford’s description of the atom. [1] The key constituent of the Bohr atomic model is the energy of the electrons are restricted to certain discrete values; that is, the energy is quantized. This means that only certain orbits with certain radii are allowed; orbits in between simply don't exist. CITATION REQUIRED
The orbitals a quantized meaning only certain orbits with certain radii are allowed; orbits in between simply don't exist. Awkward sentence [2]
The negatively charged electron in Bohr’s model, revolve around the atomic nucleus, which is positively charged. According to Coulomb's law, the negatively charged electrons revolve because of the attractive electrostatic force. [3] The electons move from each orbital. If it is at the lowest its called ground state and the highest is called excited state.
Example Bohr Model for Calcium Ion
Each discrete energy level may be designated with letters (K, L, M, N, etc).
