Atoms of the same element differ in the number of neutrons in their nuclei. All atoms of a given element have the same number of protons, of course. The number of protons in a nucleus determines which element the atom is. But the number of neutrons can vary, and these different "versions" of a given element are called isotopes of that element. See the related question, which is linked below.
No; each chemical element has different properties.
An isotope is not a chemical property; rather, it refers to different forms of an element that have the same number of protons but different numbers of neutrons. Isotopes can affect the physical properties of an element, such as its mass and stability, but they do not change its chemical properties.
Isotopes of an element have the same number of protons, which determines the element's chemical properties. The differing number of neutrons in isotopes does not significantly affect the element's chemical behavior.
The differences in chemical properties are not significant (excepting protium and deuterium); the physical properties are different.
allotrope
Because an element is an element and a molecule is a molecule; they are different chemical entities and of course they have different chemical and physical properties.

Yes, it is possible to separate isotopes of bromine by chemical means using processes such as fractional distillation or exchange reactions involving different isotopic forms of the element. These methods take advantage of the different physical or chemical properties of different isotopes to achieve separation.
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.
Yes, different isotopes of the same element have different masses.
For the same element, isotopes have equal numbers of protons but different numbers of neutrons. Isotopes of a given element have similar chemical properties due to having the same number of electrons, which determines an element's chemical behavior.
