An element is defined by the number of protons, so this cannot vary.
Isotopes of a particular element are different in the number of neutrons within the atoms. These isotopes are said to be comparatively "lighter" or "heavier" than other isotopes based on the total of protons and neutrons (Atomic Mass).
Isotopes are elements that differ in the number of neutrons they have. Isotopes of an element have the same number of protons in their nuclei but different numbers of neutrons, resulting in varying atomic weights.
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
They have the same number of protons and different number 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).
Isotopes are atoms of the same element which differ in the number of neutrons they contain. For example, helium-3 (3He), with two protons and one neutron in each nucleus, and helium-4 (4He), with two protons and two neutrons, are two different isotopes of helium. Nearly all elements found in nature are mixtures of several different isotopes. Although the chemical properties of isotopes of the same element are the same, the physical properties differ. The natural proportions of the isotopes are expressed in the form of an abundance ratio.
Isotopes
This statement is incorrect. Isotopes of an element have the same number of protons but differ in their number of neutrons. Rubidium, specifically, has two stable isotopes: Rb-85 and Rb-87, which both have 37 protons but different numbers of neutrons.
Isotopes are elements that differ in the number of neutrons they have. Isotopes of an element have the same number of protons in their nuclei but different numbers of neutrons, resulting in varying atomic weights.
Isotopes have a different number of neutrons but the number of protons and electrons is the same.

Isotopes differ by the number of protons.
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
All isotopes of an element have the same number of protons, otherwise they would not be the same element. What varies is the number of neutrons, they can be more or less than in the stable isotope(s) of the element.
Isotopes must have the same atomic number, which is the number of protons. The atomic mass, which is the total number of protons and neutrons, varies for the different isotopes. so it should have different mass numbers..
Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. An example is carbon-12 and carbon-14, which both have six protons but differ in the number of neutrons they possess.
Yes, isotopes of an element are the same element but with different numbers of neutrons in the nucleus and thus different atomic masses.
