Solved: Select the element in each pair with the higher

Solution 66 QP:Here, we are going to find out the higher ionization energy from each pair of elements.Step 1:Ionization Energy (I.E): It is the amount of energy required to remove one electron from an atom in the gaseous state.For example Na(s) + I.E Na+(g)+ e-The IE is going to decrease as we move down a group in the periodic table.Thus, the attraction of a nucleus for the outermost electrons decreases as those electrons are farther from the nucleus.Similarly, As we move from left to right in the period of the periodic table, the IE increases which is due to the increase in positive charge of the nucleus due to the increase in protons.
