Calcium’s Atomic Radius or Ionic RadiusCalcium’s ionic radius is smaller because it losses two electrons and an energy level.Therefore, the atomic radius is larger.b. Fluorine’s Atomic Radius or Ionic RadiusFluorine’s ionic radius is larger because it gains one electrons. This means it now hasmore electrons than protons making it harder to hold in the electrons and making the sizeslightly larger.c. Bromine’s Atomic Radius or Ionic RadiusBromine’s ionic radius is larger because it gains one electrons. This means it now hasmore electrons than protons making it harder to hold in the electrons and making the sizeslightly larger.d. Potassium’s Atomic Radius or Ionic RadiusPotassium’s ionic radius is smaller because it losses one electrons and an energy level.Therefore, the atomic radius is larger.
