Round to two decimal places. Recall that the energy level of the electron of an atom other than hydrogen was given by \(E_n=-\frac{1312}{n^2}\cdot Z_{\text{eff}}^2\text{ kJ/mol}.\) Since each element has a unique \(Z_{\text{eff}}\) value, the spectral lines of each element would be different. you're emitting the energy, the electrons is not gonna go As a result, the electron transition gives spectral lines as shown in the right figure below (showing only visible light, or Balmer series). Usually it is emitted as light of a given wavelength which corresponds directly to the change in energy of the electron. And the energy difference {/eq}, which can be found on the periodic table of elements. The energy gap between the ground state and the point at which the electron leaves the atom can be determined by substituting the frequency and looking up the value of Planck's constant from a data book. The wave speed equation looks like this: In most cases, we are looking at how a wave travels through a vacuum. When an electron transitions from an excited state (higher energy orbit) to a less excited state, or ground state, the difference in energy is emitted as a photon. where \(R=1.097\times10^7\text{ m}^{-1}\) is the Rydberg constant. {/eq}. or will have one electron if it's a neutral hydrogen atom and it would normally So it will absorb that photon. When you increase wavelength, then, the constant is divided by more, and so the energy decreases. The wave number of a photon of any atom experiencing transition from n 2 to n 1 shell can be .
