Atomic radius is the distance between the center of the nucleus to the outermost orbital shell of the atom. Assume the atom is like a football stadium and the nucleus of the atom is a ball placed at the center of the pitch. The atomic radius is from the center of the ball to the edge of the football stadium.
Explanation:
This atomic radius decreases from left to right of a periodic table because of increases in protons in the nucleus along the periodic table. This increased proton count has a higher attractive force on the electron orbitals of the atom. This decreases the atomic radius
The atomic radius of atoms down a column of the periodic table increase because an extra orbital shell is added to the atoms with every period down the column.

Answer:
the answer is actually A I just took it on usatestprep
Explanation:
Atomic radius can be defined as the atom's ability to one-half the distance between the nuclei of two atoms. Atomic radius is measured between two nuclei because the edge of the electron cloud is too difuse to clearly measure otherwise. Atomic radius increases down a group and to the left along a period.
