WebThe main three postulates that Neil Bohr gave about the ‘Model of the Hydrogen’ atom are: Atoms have a series of stable orbits within which electrons will exist while not emitting energy; every orbit corresponds to selected energy. Electrons will add a significant jump of one orbit to a different orbit. Planck’s equation gives the ... Web5 Apr 2024 · Complete step by step answer: We can give the postulates of Bohr’s model of an atom as follows, 1.In an atom, electrons that are negatively charged spin around the positively charged nucleus in a specific circular path known as orbits or shells. 2.Each orbit or shell contains a fixed energy and the circular orbits are called orbital shells.
