Istopes: Atoms of the same element that have the same number of protons but a different amount of neutrons.
The separation of isotopes is relatively easy for light elements as hydrogen, lithium, nitrogen etc. For elements with higher atomic weight and a small difference between the atomic masses of the isotopes the process is long and expensive. The insignificant differences between these isotopes doesn't facilitate the separation.
Each isotope of hydrogen has 1 proton in the nucleus. The difference between the isotopes lies in the number of neutrons: hydrogen-1 has 0 neutrons, hydrogen-2 (deuterium) has 1 neutron, and hydrogen-3 (tritium) has 2 neutrons.
No. By definition isotopes of an element have the same number of protons (that is what makes them uranium, for example) but different numbers of neutrons (neutral particules in the nucleus which provide mass).
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
it is the weighted average of the masses of an element's isotopes.

See the related questions below for each individual definition.
Isotopes as tracers can be easy to follow even if you are in low concentration and also by non-invasive(distructive) methods.

That`s easy. Being a Skudrna is the definition of being perfect!
There is no definition,its a made up word or it is a easy going easy saying!
Effortless, simple, sinchy.
Yes, but they have varying amounts of neutrons.
YES. The very definition of isotopes are atoms of the same element with the same number of proton (same atomic number) but different numbers of neutrons, therefore different mass numbers.
Relaxed or laid back.
Successful by an easy margin.
Especially of a tune, it is pleasing and easy to remember
