Carbon has a few isotopes. The most common naturally occurring isotope of it is C12. Mass number of it is 12.
It depends on the isotope. The most common naturally occurring isotope is 58Ni. Ni has the atomic number 28, so there are 30 neutrons in that isotope. There are four other stable naturally occurring isotopes with atomic weight 60, 61, 62 and 64. There are also around twenty unstable and radio-isotopes with atomic weights ranging from 48 to 78.
It depends on the isotope, of which carbon has three that occur naturally. Carbon-12 (about 99%) and carbon-13 (about 1%) are not radioactive; carbon-14 (trace amounts, maybe one part per trillion) is radioactive (beta decay into nitrogen-14) with a half-life of about 5700 years.
Cobalt like iron and many other metals occurs mainly in ore form and has been used in compound form to colour glass and pottery for over 2,000 years. However Cobalt-60 a radioactive isotope is artificiality produced from the stable common isotope Cobalt 59

Naturally occuring.
Carbon 12 is the most common isotope of carbon. 99.8% of all natural carbon in the universe as we know it is carbon-12
Ne-20 is the most common (91%) isotope with 10 neutrons in its nucleus. The other isotope Ne-22, with 12 neutron, is found for 9% of the naturally occurring Neon.
