Question 1 of 30
Why does atomic size increase as you go down a group on the periodic table?
A. Because the number of electron shells increases
B. Because there is more total attraction between electrons in the
shells and protons in the nucleus
C. Because the number of electron shells decreases
D. Because there is less total attraction between electrons in the
shells and protons in the nucleus
SUBMI
Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius.
