What trend is observed in atomic radius as you move down a group in the periodic table?

What trend is observed in atomic radius as you move down a group in the periodic table?

Step 1: Understand what a group is in the periodic table. A group is a column of elements that share similar properties.
Step 2: Know that as you move down a group, you are moving to elements that are lower on the table.
Step 3: Recognize that each time you go down to the next element in a group, an additional electron shell is added.
Step 4: Understand that more electron shells mean that the outermost electrons are farther from the nucleus.
Step 5: Conclude that because the outer electrons are farther away, the atomic radius (the size of the atom) increases.
