The decreasing order of ionization energy will be Mg >Al >P>K.
Ionization energy sometimes referred to as ionization potential, would be the amount of energy it takes to eliminate an electron from a single, isolated atom or molecule.
On moving top to bottom in the periodic table, ionization energy will decrease rapidly.
Al =13 (group 3)
P =15 (group 5)
Mg =12 (group 2)
K =19 (group 1)
The decreasing order of ionization energy will be Mg >Al >P>K.
