How do you calculate the ionization energy of He+?

Answer 1

Serenity Allen

Has this been done before by a lot of physical chemists and called a "Rydberg Constant"?

#R_H = DeltaH_(IE)("H")#

#=# #"13.61 eV"#

#= DeltaH_(IE)("He"^(+))#

Why can I say this? How many electrons does #"He"^(+)# have?

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
