5.Which would be larger the ionic radius or the atomic radius?

a. Calcium’s Atomic Radius or Ionic Radius

Calcium’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 Radius

Fluorine’s ionic radius is larger because it gains one electrons. This means it now has

more electrons than protons making it harder to hold in the electrons and making the size

slightly larger.

c. Bromine’s Atomic Radius or Ionic Radius

Bromine’s ionic radius is larger because it gains one electrons. This means it now has

more electrons than protons making it harder to hold in the electrons and making the size

slightly larger.

d. Potassium’s Atomic Radius or Ionic Radius

Potassium’s ionic radius is smaller because it losses one electrons and an energy level.

Therefore, the atomic radius is larger.
