A hydrogen-like ion is an ion containing only one electron. The energy of the electron in a hydrogen-like ion is given by:
where n is the principal quantum number and Z is the atomic number of the element.
Calculate the ionization energy (in kJ/mol) of the He+ ion.
I think I did this for you last night.
Z = 2^2
n = 1. Punch into the calculator and move on.
if you plug in
its wrong and i don't knwo why
It is -8,72 x 10^-21 kJ
Reason: After punching in those values you then have to convert that answer from J to kJ which 1kJ=1000J
