Answer:
Step-by-step explanation:
Neils Bohr in 1913 put forward his own model of the atoms based on the quantum mechanics originally developed by Planck.
- He assumed the Rutherford's model and suggested that the extranuclear space consists of electrons in specific spherical orbitals around the nucleus.
- His predecessors and contemporaries did not give this perspective to the atomic model.
- The orbits/energy levels are designated by letters K, L, M, N ....
- The maximum number of electrons that can be accommodated by an energy level is 2n² where n is the principal energy level.
