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.
All isotopes do have the same chemical properties as they have same number of protons in the nucleus and same number of electrons around the nucleus.
Yes, because they are the same element. Only (some) physical properties differ.
The physical properties are different but the differences are generally nonsignificant; excepting hydrogen isotopes chemical properies remain unchanged.
This minor effect is visible especially for light elements.
They have all the chemical, physical, nuclear properties identical. This is not the case for isotopes.
The differences in chemical properties are not significant (excepting protium and deuterium); the physical properties are different.
The number of neutrons is different; the differences between physical properties exists but are extremely small.
elements in the same group
The elements in the same groups usually do. Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
They have all the chemical, physical, nuclear properties identical. This is not the case for isotopes.
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.
The differences in chemical properties are not significant (excepting protium and deuterium); the physical properties are different.
An element is the basic purist substance , it is composed of atoms of same kind ,not of elements hence an element can't be separated in elements , your question is wrong . A compound can be separated in component elements .
Elements with same functional group have same chemical properties. They possess different physical properties.
The number of neutrons is different; the differences between physical properties exists but are extremely small.
Elements in the same group have similar properties as they have the same number of valence electrons.
elements in the same group
Elements in the same group have similar physical and chemical properties.
The elements in the same groups usually do. Elements in the same group have same number of valence electrons and hence have similar chemical and physical 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.
