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.
Isotopes have the same number of protons and electrons but the number of neutrons is different.
If an atom of the same element has the same number of protons but a different number of neutrons, then they are isotopes.
Isotopes are atoms of the same elements with different number of neutrons.
Isotopes are atoms of the same element, having the same number of protons but different number of neutrons.
The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses.
Isotopes have the same amount of protons but a different amount of neutrons.
If an atom of the same element has the same number of protons but a different number of neutrons, then they are isotopes.
Isotopes of the same element have different numbers of neutrons and mass.
Isotopes are atoms of the same element that are only different by the number of neutrons they have
Two different isotopes of the same atoms have the same number of protons and electrons; the number of neutrons is different.
Atoms have isotopes: it is true, the isotopes of the same element have different number of neutrons.
Two different isotopes of the same atoms have the same number of protons and electrons; the number of neutrons is different.
Isotopes are atoms of the same elements with different number of neutrons.
Isotopes are atoms of the same element, having the same number of protons but different number of neutrons.
Isotopes of the same element have a different number of neutrons.
All isotopes of carbon have the same number of protons and electrons; but they have a different number of neutrons.
