Isotopes of an element have nuclei with the same number of protons (the same atomic number) but different numbers of neutrons Neutrons (:
The distributive requires three numbers (or elements) and two different mathematical operations. Two numbers are not enough to illustrate it.
The main reason is that many elements exist in several isotopic forms. These are atoms with the same number of protons and electrons but different numbers of neutrons. Since the atomic mass is essentially based on the number of protons and neutrons in each atom, the element will exist in several forms with different masses. The atomic mass is the average of the masses of these isotopes, weighted together according to their abundance.
equal sets with exactly the same elements and number of elements.equivalent sets with numbers of elements
The average of a set of numbers is the sum of the numbers in the set divided by the number of elements in the set.

Isotopes differ in the number of neutrons they possess.
The isotopes of the same element has the same atomic number. But the mass number (atomic mass) is different.
The atomic number of the isotopes of an element is identical; the mass number is different.
Isotopes of an element have different masses because their nuclei have different numbers of neutrons.
Because of the difference in mass number. Isotopes must have different numbers of neutrons.
They have different numbers of neutrons, which changes the atomic mass and nuclear properties.
Isotopes have different numbers of electrons, but not different atomic numbers (numbers of protons) or they'd be different elements.
It can if isotopes are present. They can contain different numbers of neutrons in the nucleus.

Elements can exist in the form of different isotopes. Isotopes of the same element have the same number of protons in their nuclei but have different numbers of neutrons. The first gives them the same atomic number and chemical properties while the second gives them different atomic weights.
No. By definition isotopes of an element have the same number of protons (that is what makes them uranium, for example) but different numbers of neutrons (neutral particules in the nucleus which provide mass).
Mass numbers of isotopes are different.
