An isotope has same number of protons but a different number of neutrons as the original element in the atomic nucleus; it has the same atomic number as the element which isn't an isotope, but will have a different mass number.
-atomic number
The atoms of all isotopes of a given element have the same number of protons, but different numbers of neutrons. If they are neutral atoms, the number of protons will equal the number of electrons.
the same number of protons.

Atomic Number.
all isotopes of same element have same number of protons
The same number of protons
protons
Yes
isotopes of a given element differ in the number of neutrons they have.
number of neutrons and mass
Yes.
Isotopes of a given element all have the same number of protons. They differ in their number of neutrons.
Atomic mass number is the average atomic mass for that element, which is : All the isotopes' masses known for that element averaged up. Atomic number is the element's "identity", the number of protons the element and all its isotopes have. All the isotopes of a given element will have different number of electrons and neutrons, but the protons of the element never will change.
isotopes of a given element differ in the number of neutrons they have.
Isotopes.
number of neutrons and mass
Yes.
No. The most common isotope(s) of an element are often stable.
The identity of a chemical element is given by the number of protons.
Isotopes of a given element all have the same number of protons. They differ in their number of neutrons.
They are called as isotopes of the given element.
Atomic mass number is the average atomic mass for that element, which is : All the isotopes' masses known for that element averaged up. Atomic number is the element's "identity", the number of protons the element and all its isotopes have. All the isotopes of a given element will have different number of electrons and neutrons, but the protons of the element never will change.
In that they have different masses due to difference in neutrone number
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 number of neutrons for any given element varies, depending on the isotopes. Search the Wikipedia, or Google, for "Isotopes of Zirconium" for the isotopes of this particular element. The list of isotopes will give you the atomic mass (protons + neutrons) for the different isotopes; subtract the atomic number (which is the number of protons) to get the number of neutrons for each isotope.
