do isotopes of an element have the same chemical and physical properties?

Answer 1

Chemical - yes.

Physical - no.

Due to the fact that different isotopes have different number of neutrons the wight of a cubic inch of one isotope is slightly different than the wight of a cubic inch of another isotope. The fact that one isotop is heavier than another allows us to separate isotopes using a centrifuge. Also some isotopes of an element are radioactive while others isotopes of the same element are not.

Answer 2

Isotopes have different numbers of neutrons which change the mass of the atom and therefore the physical properties of the atom. Chemical properties are determined by the number and arrangement of electrons which is the same for all isotopes of the same element.

Answer 3

Depends a bit on how far you want to go with this. They do not have the same physical properties since they have different numbers of neutrons, and can be distinguished by a number of types of measuring techniques (like NMR, nuclear magnetic resonance). Also, if you consider deuterium (the stable isotope of hydrogen), D2O ("heavy water") is quite different than normal H2O (see the reference below).

On the other hand, isotopes of an element will form the same kinds of chemical bonds and their chemical reactions are quite similar.

Answer 4

Yes, isotopes have the same chemical properties but not the same atomic weight.

Answer 5

Generally speaking, there are very, very slight differences in chemical behavior. The most marked of these differences happens between hydrogen and deuterium.

There are slight physical differences as well, but not very much. Once again, H and D would show the greatest physical differences.

There are slight differences in the positioning of the spectral lines as well.

Answer 6

For natural elements, most do the have same properties. 1H2 or deuterium does have notably different properties than 1H1 (it is twice as dense for starters). D2O, the analog of regular water does have slightly different properties than does water.

Answer 7

yep.. they are just either heavier or lighter..

and just a side note, they have different nuclear properties and stabilities.
