- i want to find the first ionization energy for lithium using Bohr formula but something seems wrong !

- Homework Equations
- Bohr energy equation

i am trying to calculate the first ionization energy for lithium with this equation but it seems to work only with hydrogen ?

i put nf = infinity and ni =2 ,and z = 3 for lithium and it gives about 30 ev not 5.39172 ev which is the value for lithium :

i will appreciate any help in this
