Question

Found in the gas phase the Be⁺³ cation has an energy level formula analogous to that of the hydrogen atom, since both species have only one electron. The energy levels of the Be⁺³ ion are given by the equation

E_n = -21001/n² kJ/mol, where n = 1, 2, 3....

First Find the wavelength in nm of the line emitted when the electron jumps from the n = 2 level to the n = 1 level using the equation

wavelength (in nm) = (1.19627 x 10⁵) / (energy change in kJ/mol) then find E_infinity for Be³⁺ in kJ/mol?
