No they don't have.
Isotopes of an element differ in mass from from each other and this is due to the different no. of electrons in their nucleus.
Two different isotopes of an element have different numbers of neutrons. That's what an isotope is. So, no, isotopes of an element can not have the same 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.
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
Isotopes of the same element have different number of neutrons.
The difference between isotopes of the same element have to do with the number of neutrons present in the nucleus of the atom. Isotopes are atoms of an element that contain the same number of protons, but different numbers of neutrons and therefore different mass.
Atoms have isotopes: it is true, the isotopes of the same element have different number of neutrons.
Atoms of the same element that differ in the number of neutrons they contain are known as isotopes.
Isotopes of the same element have the same number of protons and electrons, but varied numbers 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 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.
