Solution

  1. Ionization energy is depicted as the energy needed to withdraw an electron from the outermost shell of an isolated gaseous atom.
  2. The first ionization energy of Lithium is 520kJmol-1.
  3. The electronic configuration of Lithium is 1s22s1.
  4. The electrons belonging to the s-subshell lie close by to the nucleus. So, eliminating an electron from the 2s orbital is hard.
  5. Hence, additional energy is imposed to eliminate the electron.
  6. Consequently, the ionisation energy of Lithium is significantly high.
