Ionization energy

Can anyone tell me which formula is used to calculate the ionization energy of elements different then H.

E= Z^2 13,6eV/ n^2 where n- number of the shell, and Z- number of protons

only gives the ionization energy in case of one electron around the nucleus.

Thank you in advance.

Konain the formula you quote would be for a single electron bound to a nucleus of atomic number Z. But in an atom it will have Z electrons and they interact so the ionisation energy is much more complex to calculate. The first good results from a calculation was by Hartree and Fock - look up Hartree model in a search engine
