Introduction to Modern Inorganic Chemistry.Planck's constant, h, can be used in terms of Joule(s) or eV(s). Ephoton/h h Planck's constant 6.627x10-34 Js This formula can be used to determine the energy of a photon if you know the frequency of it. Higher orbit to a lower orbit and absorbed whenĤ) The energy and frequency of light emitted orĪbsorbed is given by the difference between theĮphoton Efinal - Einitial This formula can be used to determine the energy of the photon emitted () or absorbed(-). These orbits are stable and calledĢ) Each orbit has an energy associated with it.įor example the orbit closest to the nucleus hasĪn energy E1, the next closest E2 and so on.ģ) Light is emitted when an electron jumps from a The Bohr model consists of four principlesġ) Electrons assume only certain orbits around Treated only H atom (one electron system).Used a combination of classical and quantum.Each shell can only carry a set number of.The number of Protons Number of Electrons.Forĭraw the Dot Cross diagrams for the following With Dot Cross diagrams elements and compoundsĪre represented by Dots or Crosses to showĮlectrons, and circles to show the shells.
