Screenshot of carbon isotope data.  Half-life period column is blank.

Also, why are there so many isotopes listed?  carbon-8?  carbon-20?  Surely
these can't even be made?

Hello

Where do you see Carbon -20? What does the -20 mean?

About your questions: These isotopes are either natural or have been produced in laboratories, even though often only for splitseconds.

the german wikipedia writes something about that:
http://de.wikipedia.org/wiki/Liste_der_Isotope/2._Periode#6_Kohlenstoff
For C-8, i agree, but C-20 has a realy long halflife (0.014s)
I'll add the rest of the data soon. Perhaps i'll find a reasonable lower bound for the halflifes of Kalzium's isotopes.

P.S. Carsten says that the halflife-bug is fixed now.

The units are now displayed.
