Technetium is a chemical element with the atomic number 43 and the symbol Tc. It is the lightest element, and all of its isotopes are radioactive; none are stable, with the exception of 97Tc in its completely ionized state. The isotope 99TC is the most common in nature. Nearly all Technetium is synthesized, and only around 18,000 tones can be found in the earth's crust at …

Technetium, with the atomic number 43 and symbol "Tc," is regarded as the first-ever artificially-produced element, although there are a few isotopes of technetium that are naturally occurring. It is also the lightest element on Earth, and all of its isotopes are radioactive. For its naturally-occurring isotopes, they are typically produced through spontaneous fission in

Technetium is a chemical element with atomic number 43 which means there are 43 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.
