Tc, as in Technetium...dimonds
The price of technetium has gone down because there wasnt much technetium in the 1950s which made it rare and expencive but now there are more power stations now than there was before which produce technetium so there is more about and has reduced in price.
Space made hydrogen first...but technetium wat the first man made
Technetium which has an atomic mass of 98.
Technetium exist in nature only in ultratraces; being unstable technetium technetium was lost by radioactive decay.
