An isotope of an element has the same number of protons but a different number of neutrons. One of the most common is deuterium (heavy water), an isotope of hydrogen that has one neutron instead of the usual zero.
An isotope.
They have the same number of protons and different number of neutrons.
Each element has a unique number of protons. If another atom has the same number of protons as that element, it is the same element.
Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.
The isotopes of an element are alike in that they have the same number of protons, electrons, and the same chemical properties. The isotopes are different in that they have different numbers of neutrons and thus different atomic masses.
The isotopes of an element have the same number of protons, but different numbers of neutrons.
Isotopes are atoms of the same element, having the same number of protons but different number of neutrons.
They have the same number of protons and different number of neutrons.
Isotopes are atoms of the same element, having the same number of protons but different number of neutrons.
Each chemical element has a different number of protons; the number of neutrons can be similar.

Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.
It is an isotope of the element.
The number of protons an atom has depends on which element it is. Every element has a different number of protons. And within each element, there will be a different number of neutrons, creating isotopes.
Isotopes have the same amount of protons but a different amount of neutrons.
The isotopes of an element are alike in that they have the same number of protons, electrons, and the same chemical properties. The isotopes are different in that they have different numbers of neutrons and thus different atomic masses.
Isotopes of an element have the same number of protons but differing numbers of neutrons in the nucleus.
Isotopes are different forms of the same element which have different numbers of neutrons in their atomic nuclei. A given element is identified by the number of protons in its nucleus; that's its atomic number. Two different isotopes of the same element have the same number of protons, but each has a different number of neutrons in its nucleus. Different isotopes of the same element are chemically the same.
