Atoms are complicated than hydrogen have...

Atoms are complicated than hydrogen have more than one proton in their nucleus. Let z stands for the number of protons in a nucleus. Also imagine that an atom loses all but one of its electrons so that it changes into a positively charged ion with just one electron. Bohr.s formula for the energy levels of the hydrogen atom can easily be changed to apply to such ions
What minimum amount of energy is required to bring an electron from ground state of `Be^(3+)` to infinity

A

`4.358 xx 10^(-18)`

B

`2.179 xx 10^(-18)`

C
