The charge on boron atom should be +4. Then B4+ contains only one electron and becomes isoelectronic with hydrogen. Hence B4+ can be treated as hydrogen like ion. For example like H atom, B4+ ion will follow Bohr's theory.

Say you have a point charge of one Coulomb and a hydrogen atom some distance away. Within what distance would the difference of forces on the proton and electron from the Coulomb charge exceed the attraction between the proton and electron that holds the hydrogen atom together. Treat the hydrogen atom as a proton and electron 0.53 × 10−10 m (a.k.a., one Bohr radius) apart
