Why must different isotopes of the same element have different physical properties?

Isotopes are atoms of an element having different numbers of neutrons. The Atomic Mass of an atom is approximated by the number of neutrons plus the number of protons; it follows, then, that isotopes of an element differ in their atomic masses.
Mass itself is a physical property. Other properties related to mass also vary by isotope: density (mass/volume), boiling point, freezing point, and the degree of ion deflection in a mass spectrometer are perhaps the most obvious of these related properties. The rate of diffusion is also affected; as per Graham's law of effusion, the rate of diffusion of a gas is inversely proportional to the square root of its molecular mass. (This property played a crucial role in the development of the atomic bomb.)

How do the physical properties of isotopes of the same element compare?
The number of neutrons is different; the differences between physical properties exists but are extremely small.
Does isotopes affect the physical properties of the element?
Isotopes contribute to the atomic weight of a chemical element.
Is isotopes of same element have same properties?
The differences in chemical properties are not significant (excepting protium and deuterium); the physical properties are different.
Isotopes of the same element have differnt?
Different numbers of neutrons and hence different physical properties.
Why do isotopes of the same element have the same chemical behavior?
Chemical properties of a element is governed by ELECTRONIC CONFIGURATION of that element. As isotopes of same element have identical electronic configurations, their chemical properties are same.

Does isotopes affect the physical properties of the element?

What is different about the isotopes of a particular element?
The number of neutrons in the atoms. This affect some physical properties.
Isotopes of an element differ from each other in the number of?
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
Is isotopes of same element have same properties?
The differences in chemical properties are not significant (excepting protium and deuterium); the physical properties are different.

Different numbers of neutrons and hence different physical properties.

What is the relationship between atoms ad isotopes?
A natural chemical element may be monoisotopic or has isotopes. Isotopes are atoms but they differ from other isotopes by the number of neutrons. This involve a different atomic mass and different physical properties or sometimes (for light isotopes) different chemical properties. Also, all chemical elements have radioactive, artificial isotopes.
What is true about the number of protons and nuetrons in an isotope?
Isotopes of an element have same number of protons and different number of neutrons. Hence similar in chemical properties and different in physical properties.
What is true about all the isotopes of an element?
All isotopes of an element have the same number of protons. When they are not ionic, they have the same number of electrons. And, for all practical purposes, they behave identically as chemicals. share most of the same physical properties, and chemical properties. They have different number of neutrons.
Do isotopes with the same elements have the same physical properties?
The physical properties are of course different. The chemical properties are considered identical but this is not a general rule; for example hydrogen isotopes (1H and 2H) have some different chemical and biochemical properties.
How could physicists propose an element to put in a periodic table if sometimes like uranium have different atomic number and atomic mass?
The atomic number of the isotopes of an chemical element is the same; only the atomic mass of the isotopes is different. Also the isotopes of an element have the same chemical and physical properties (of course with some approximation).
