if you mean isotopes then isotopes of the same element have a different number of neutrons in the nucleus so have a different atomic weight.
Isotopes of the same element have different numbers of neutrons and mass.
Yes, isotopes of an element are the same element but with different numbers of neutrons in the nucleus and thus different atomic masses.
Yes, different isotopes of the same element have different masses.
Isotopes are atoms of the same element that are only different by the number of neutrons they have
No, isotopes of the same element are of different weight.
Atoms of the same element that have different masses are called isotopes of the element. The presence of different numbers of neutrons in the nucleus is responsible for the existence of isotopes of an element.
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
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.
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 mass number would be different for different isotopes of the same element.
Isotopes of the same element have a different number of neutrons.
They may come from different isotopes of the same element, but not from the same atom.
