Question

Exercise 9.110 Part A Would you expect the same behavior in sodium? When atoms lose more than one electron, the ionization energy to remove the second electron is always more than the ionization energy to remove the first. Similarly, the ionization energy to remove the third electron is more than the second and so on. However, the increases in ionization energy upon the removal of subsequent electrons is not necessarily uniform. For example, consider the first three ionization energies of magnesium: First ionization energy 738 kJ/mol Second ionization energy 1450 kJ/mol Third ionization energy 7730 kJ/mol The second ionization energy is roughly twice the first ionization energy, but then the third ionization energy is over five times the second.

Answer 1

For first 3 Ionisation Energies (lE) are

First IE = 496 KJ/mol

second lE = 4563 KJ/mol

Third lE = 6913 KJ/mol

So NO , same behaviour not occurs for sodium

because after removal of 1st electron, it get inert gas configuration so value of second IE Is very large as compared to first one.
