The number of neutrons is different; the differences between physical properties exists but are extremely small.
Isotopes contribute to the atomic weight of a chemical element.
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.
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.
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.

Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
The number of neutrons in the atoms. This affect some physical properties.

The physical properties of a compound may be entirely different from the physical properties of the elements from which the compound is made.

The atomic number is the same for the all isotopes of a chemical element.
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.
There are many physical properties; density, thermal and electrical conductivity, colour, presence of allomorphs (differing forms, such as in carbon), isotopes, radioactivity, malleability or ductility, hardness. And many more.
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.
