Given information
The pair of elements and .
Step-by-step explanation
Step 1.
Ionization energy is the energy required to remove electrons from the outermost shell of an isolated gaseous atom.
In a periodic table across the period from left to right atomic size decreases hence it will be difficult to remove electrons thus ionization energy increases across a period from left to right. Ongoing down the group atomic size increases and ionization energy thus decreases.
