Question

Where do you find the atoms with the largest atomic radius on the periodic table? (1 point)
• the lower right
• the upper lett
• the bottom left corner
O the upper right

Answer 1

You find the atoms with the largest atomic radius in the **bottom left corner** of the periodic table. As you move down a group, the atomic radius increases due to the addition of electron shells, and as you move to the left across a period, the atomic radius also generally increases due to the decrease in effective nuclear charge felt by the outermost electrons.
