How many valence electrones does Rn have? - Answers
WebElectrons in higher energy levels have a higher energy than those in lower energy levels. When an electron transitions to a lower state, a photon is emitted, the energy of which is equal to the energy difference between the energy levels it is moving between. This means that transitioning from a higher energy level to a ground state (such as ... WebAug 14, 2024 · The speed which light travels in a vacuum is the same for all forms of electromagnetic radiation, c = 2.997 × 108 m s. As such, we can relate the frequency of light to the wavelength of light by the equation. λ(m) × ν(s − 1) = c(m s) The longer the wavelength λ, the lower the frequency ν.
