It's the atomic number for technetium.
However, technetium does not even have one stable isotope.
And of course, the answer is technetium.

It depends on which molecule the technetium is.
Period 5 also includes technetium, the lightest exclusively radioactive element.
The first such element being Technetium in 1937.
Technetium Tc-99m decays by isomeric transition with a physical half-life of 6.01 hours.
The use of radioactive iodine or technetium- method based on.
Technetium also has numerous nuclear isomers, which are isotopes with one or more excited nucleons.

One is, for instance, technetium is a radioactive element with a decay time of 4.2 million years.
Thyroid scan: During this study,a small amount of radioactive iodine or technetium is injected through the mouth or into a vein.
Technetium, with atomic number(denoted Z) 43, is the lowest-numbered element in the periodic table that is exclusively radioactive.
The lightest element consisting of solely radioactive isotopes in Technetium, which is also the first artificially made element.
Technetium, with atomic number(denoted Z) 43, is the lowest-numbered element in the periodic table for which all isotopes are radioactive.
As it turns out, nearly every element from Hydrogen(Z=1) to Bismuth(Z=83)has at least one stable isotope, with Technetium(Z=43) and Promethium(Z=61) as the exceptions.
Long-lived technetium isotopes produced commercially are by-products of fission of uranium-235 in nuclear reactors and are extracted from nuclear fuel rods.
One of the things that I study out here in The Irish Sea… is that I go out with my colleagues andwe search for something called Technetium 99. Which is a radioactive material.
If you suddenly observe technetium in a sun-like star, you can be sure that somebody has put this element in the atmosphere, because in a natural way it is impossible to do this.

In 1937, technetium(specifically the technetium-97 isotope) became the first predominantly artificial element to be produced, hence its name(from the Greek τεχνητός, meaning"artificial",+-ium).
However, they are sometimes called synthetic anyway.[2] The first, technetium(Tc), was created in 1937.[3] Plutonium(Pu, atomic number 94), first made in 1940, is another such element.
Because no isotope of technetium has a half-life longer than 4.2 million years(technetium-98), the 1952 detection of technetium in red giants, which are billions of years old, helped to prove that stars can produce heavier elements.
