What is true of technetium?

Answer 1

The element technetium is an "artificial" element. This odd metal has no stable isotopes, so any that existed on earth long ago has decayed and vanished. It was created in experiments in the Berkeley cyclotron facility, but was isolated by a pair of Italian scientists who isolated it from materials sent them from the California facility.

Answer 2

A radiosotope is a radioactive isotope; and isotopes are atoms having the same number of protons but a different number of neutrons.

Technetium has a huge number of isotopes and isomers.

Answer 3

Technetiumis the chemical element with atomic number 43 and the symbol Tc. It is the lowest atomic number element without any stable isotopes; every form of it is radioactive. Nearly all technetium is produced synthetically, and only minute amounts are found in nature. Naturally occurring technetium occurs as a spontaneous fission product in uranium ore or by neutron capture in molybdenum ores. The chemical properties of this silvery gray, crystallinetransition metal are intermediate between rhenium and manganese.

Answer 4

nonmetal
