Atomic and Ionic Radii

What is the trend of atomic radius in the periodic table?

• The trend of atomic radius is random and does not follow any pattern.

• The trend of atomic radius is decreasing from left to right and increasing from top to bottom.

• The trend of atomic radius is constant across the periodic table.

• The trend of atomic radius is increasing from left to right and decreasing from top to bottom.

What is the trend of ionic radius in the periodic table?

• Ionic radius generally decreases across a period and increases down a group.

• Ionic radius generally increases across a period and remains constant down a group.

• Ionic radius remains constant across a period and increases down a group.

• Ionic radius generally increases across a period and decreases down a group.

What are the factors affecting atomic radius?
