Which order of ionization energy is correctans.Mg > AlSi = PSi > PMg < Al Previous Marked for Review Next

The order of ionization energy is determined by the ease with which an atom or molecule can lose an electron to form a positive ion. The greater the ionization energy, the harder it is to remove an electron.

1. Compare Mg and Al: Magnesium (Mg) has a lower ionization energy than Aluminum (Al) because Mg is located to the left of Al in the periodic table. So, Mg < Al.

2. Compare Si and P: Silicon (Si) has a lower ionization energy than Phosphorus (P) because Si is located to the left of P in the periodic table. So, Si < P.

Therefore, the correct order of ionization energy is Mg < Al and Si < P.
