Question

Would an element's isotopes vary in their atomic radii?

1) Yes
2) No
3) Not enough information to determine

Answer 1

Yes, an element's isotopes can vary in their atomic radii.

Step-by-step explanation:

Yes, an element's isotopes can vary in their atomic radii. Isotopes are atoms of the same element that have different numbers of neutrons. Since the number of neutrons affects the mass of the atom, isotopes of the same element can have different atomic masses and thus different atomic radii. For example, carbon-12 and carbon-14 are both isotopes of carbon, but carbon-14 has more neutrons and therefore a slightly larger atomic radius than carbon-12.
