The energy needed for the following process is 1.960 × 104kJ/mol:
Li(g) → Li3+(g) + 3e−
If the first ionization energy of lithium is 5.20 × 102 kJ/mol,calculate the second ionization energy of lithium—that is, theenergy required for the process:
Li+(g) → Li2+(g) + e−
A hydrogen-like ion is an ion containing only one electron. Theenergies of the electron in a hydrogen-like ion are given by
En = −(2.18 × 10−18 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)
