Compared to atoms of the same element, isotopes have different


A. numbers of neutrons.
B. numbers of protons.
(C. types of subatomic particles.)
D. numbers of electrons.

A

Isotopes have different number of NEUTRONS.

The correct answer is A. numbers of neutrons. Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. This means that isotopes of an element have different atomic masses but the same atomic number. To determine the difference in isotopes, you need to look at the number of neutrons in the nucleus of the atom. This information can be found on the periodic table, where the atomic mass is given for each element. By subtracting the atomic number (which represents the number of protons) from the atomic mass, you can calculate the number of neutrons in an atom of that element.
