Chemistry

The energy needed for the following process is 1.960 Ã— 104kJ/mol:
Li(g) â†’ Li3+(g) + 3eâˆ’
If the first ionization energy of lithium is 5.20 Ã— 102 kJ/mol,calculate the second ionization energy of lithiumâ€”that is, theenergy required for the process:
Li+(g) â†’ Li2+(g) + eâˆ’
A hydrogen-like ion is an ion containing only one electron. Theenergies of the electron in a hydrogen-like ion are given by
En = âˆ’(2.18 Ã— 10âˆ’18 J) (Z2)(1/n2)
where En is the energy of the electron in the hydrogen-like ion,n is the principal quantum number, and Z is the atomic number ofthe element.
Second ionization energy of lithium:Â Â kJ/mol (Enteryour answer in scientific notation)
