Question

Lithium is considered a hydrogen-like atom because it has one valence electron. Calculate the energy required to completely remove the valence electron from a lithium atom in its ground state. Find the wavelength of light that has enough energy in a single photon to achieve this.

Accepted Answer

E = 4.90×10^–18 J; λ = 40.6 nm
