Calculate the energy (in kJ/mol) required to remove the electron in the ground state for each of the following one-electron species using the Bohr model.
(a) He+


(b) Li2+

  • Chemistry -

    For He^+,
    E = 2.180E-18 J*Z^2(1/n2)
    Z is the atomic number of He. n is the principal quantum number of the for the one remaining electron. This will give you J per photon. You need to multiply by 6.02E23 for J/mol then convert to kJ/mol.
