Question

How do different isotopes of the same element compare?

Answer 1

Well, the isotopes certainly have the same number of nuclear protons, fundamental, positively-charged nuclear particles.

Explanation:

And for more details see the following site with respect to the isotopes of hydrogen. The hydrogen isotopes are highly useful species to interrogate when we characterize typical organic compounds because (i) they have different magnetic properties, and may be examined by `"NMR spectroscopy"`, and (ii) the different masses of `""^1H` versus `""^2H`, versus even `""^3H` allows us to examine organic compounds by mass spectroscopy.

On the other hand, the `""^13C` is of small abundance compared to `""^12C`; nevertheless `""^13C{""^1H}` `"NMR spectroscopy"` is now a routine, straightforward, and powerful means of characterization even with compounds with natural abundance of `""^13C` nuclei.

Answer 2

Isotopes of same element have same chemical properties but different mass related properties.

Explanation:

As isotopes(atoms of same element having same atomic number but different mass number) have same number of electrons therefore shows similar chemical properties.

But, the mass no.(no.of neutrons+no.of protons) are different.Therefore Isotopes have different mass related properties.
