Question
Which of the following trends is observed as you move down a group in the Periodic Table?Group of answer choicesElectronegativity increasesIonization energy increasesAtomic radius decreasesAtomic radius increases
Solution
As you move down a group in the Periodic Table, the atomic radius increases. This is because each row down adds a new electron shell to the atoms. More electron shells mean a larger atomic radius. The other options are incorrect: Electronegativity and ionization energy typically decrease as you move down a group, and the atomic radius certainly does not decrease.
