Web27 Jul 2024 · The energy emitted or absorbed by the atoms and molecules will be in the form of discrete packets of energy called quanta. The energy of quanta (E) is proportional to its frequency (v).E ∝ v or E=hv. where h is the Planck’s Constant (6.626 × 10-34 Js). The energy of quanta is quantised, thus, E=hv. Bohr’s Atomic Model(1913) WebBohr suggested that the atom had quantised energy levels around it that were the only places an electron was allowed to be in. To derive this he simply postulated that the angular momentum of the electron has to be some integer multiple of Planck’s constant (6.626x10 -34 m 2 kg/s) over 2π.
