# Energy states and electron excitation

We all know that in Bohr's model for hydrogen like species , electrons can revolve in only those orbits where its angular momentum is an integral multiple of $\hbar=h/2\pi$. But suppose we provide the electron in hydrogen atom ground state an energy such that its resultant total energy doesn't match with any of the higher orbit energies. Will it jump to a higher level or the energy will not be utilized?

• How come so many still refer to the Bohr Model? Do some education systems lag behind current theory that much? – Gert Nov 8 '16 at 20:57

First, the Bohr atom model is not correct. Its lowest energy state has angular momentum $\hbar$. But this is not further relevant here.
