Yes, isotopes have different physical properties.
Isotopes are exactly same with respect to all the chemical properties but they differ with respect to physical properties.
All isotopes of a substance are chemically the same. It is their physical properties which are different.
Only the nuclear properties of the hassium isotopes were determined.
Isotopes contribute to the atomic weight of a chemical element.
The number of neutrons is different; the differences between physical properties exists but are extremely small.
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.
The differences in chemical properties are not significant (excepting protium and deuterium); the physical properties are different.
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.
The number of neutrons in the atoms. This affect some physical properties.
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
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.
They have all the chemical, physical, nuclear properties identical. This is not the case for isotopes.
