Question

atom a and atom b have the same number of protons, but they do not have the same number of neutrons. which statement describes these atoms? atom a and atom b are isotopes of the same element. atom a and atom b are different elements. atom a and atom b have different atomic numbers. atom a and atom b have the same mass number.

Explanation:

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. Since Atom A and Atom B have the same number of protons but different numbers of neutrons, they are isotopes of the same element. Atomic number is determined by the number of protons, so they have the same atomic number. Mass number is the sum of protons and neutrons, so they have different mass numbers.

Answer:

Atom A and Atom B are isotopes of the same element.
