Question

Compared to a neon atom, a helium atom has a smaller atomic radius

Answer 1

Answer:

True

Explanation:

Atomic radius is the distance between the central nucleus of an atom to the outermost shell (containing electrons). Generally, atomic radius increases down a group and the situation in the question is no exception. The increase down a group is because of the increase in electron shell down a group.

Helium (He) has just one electron shell while Neon (Ne) has two electron shells. The distance between the nucleus and the second electron shell of neon is higher than the distance between the nucleus and the single electron shell of helium.
