Isotopes have a different number of neutrons, and neutrons have weight-on a molecular level.
Isotopes are atoms of the same element that have different numbers of neutrons in their nuclei. This leads to variations in atomic mass for isotopes of the same element.
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.
The isotopes of an element have the same number of protons, but different numbers of neutrons.
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
neutrons
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
Isotopes of the same element have a different number 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 number of neutrons.
Isotopes are atoms of the same element that have different numbers of neutrons in their nuclei. This leads to variations in atomic mass for isotopes of the same element.
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.
Yes, isotopes of an element are the same element but with different numbers of neutrons in the nucleus and thus different atomic masses.
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.
Isotopes of the same element have different numbers of neutrons.
They are isotopes of that element, they have different neutron numbers.
Isotopes of the same element have the same number of protons and electrons, but varied numbers of neutrons.
