isotope applications, in particular those of stable isotopes

Isotopes Chlorine has a wide range of isotopes.

As a rule, there is only a handful of stable isotopes for each of these elements, the average being 3.2 stable isotopes per element.

Besides these stable forms, there are over 40 unstable isotopes that have been studied.

Isotopes Naturally occurring titanium is composed of 5 stable isotopes 46Ti, 47Ti, 48Ti, 49Ti, and 50Ti, with 48Ti being the most abundant (73.8 natural abundance).

Elements 43, 61, and all elements numbered 83 or higher have no stable isotopes.

Isotopes Natural ytterbium is composed of seven stable isotopes 168Yb, 170Yb, 171Yb, 172Yb, 173Yb, 174Yb, and 176Yb, with 174Yb being the most abundant isotope, at 31.8 of the natural abundance).

Though not understood at the time by Thomson, this was the first discovery of isotopes of stable atoms.

Twenty six elements have only a single stable isotope, while the largest number of stable isotopes observed for any element is ten, for the element tin.

Natural boron is composed of two stable isotopes, one of which (boron 10) has a number of uses as a neutron capturing agent.

The nucleus of deuterium, called a deuteron, contains one proton and one neutron, whereas the far more common hydrogen isotope, protium, has no neutron in the nucleus.

Plutonium isotopes are expensive and inconvenient to separate, so particular isotopes are usually manufactured in specialized reactors.

Although non exploding red giants can produce significant quantities of elements heavier than iron using neutrons released in side reactions of earlier nuclear reactions, the abundance of elements heavier than iron (and in particular, of certain isotopes of elements that have multiple stable or long lived isotopes) produced in such reactions is quite different from that produced in a supernova.

You were delirious.
