Question

se Rydberg's equation for the energy of an electron to find the equation for the ANGE of energy of an electron undergoing a transition between energy levels (initial energy level of ni to a final energy level of ni). Eelectron = -2.178 x 10-18 AE electron = ???

Answer 1

Answer -

Given,

E_electron = -2.178 * 10^-18(z²/n²) J

where , n = energy level

z = atomic number

We have to find the equation for the change in energy from initial level to final level

Change in Energy = Energy at Final Level - Energy at initial Level

So, Energy at final level (n_f) = = -2.178 * 10^-18(z²/n_f²) J

Energy at Initial level (n_i) = = -2.178 * 10^-18(z²/n_i²) J

Change in Energy ($\Delta$E_electron) = -2.178 * 10^-18 * z² * [(1/n_f²) - (1/n_i²) ] J [Answer]
