Atom A and Atom B have the same number of protons and neutrons, but they do not have the same number of electrons.

Which statement describes the atoms?

A. The atoms have the same chemical symbol.
B. The atoms have the same charge.
C. The atoms have different atomic numbers.
D. The atoms have different atomic masses.



Answer :

Final answer:

Isotopes have the same atomic number but different atomic masses due to varying numbers of neutrons.


Explanation:

Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. This results in different atomic masses for isotopes of the same element, even though they have the same atomic number.

Isotopes exhibit the same chemical behavior due to the same number of protons and electrons. The differences in neutrons exclusively lead to differences in mass numbers among isotopes.
