There are a lot more than 2 radio active isotopes... To answer this question a naturally or created radioactive element needs to be mentioned.
The stable carbon isotopes are carbon-12 & carbon-13. There are several other unstable isotopes.
Uranium has 29 known isotopes and isomers (3 natural and 26 artificial). Two other isotopes are not still confirmed. For all elements heavier than Bismuth, all their isotopes are radioactive.
All carbon isotopes have the same number of neutrons.
what are two radio active isotopes that are usful for dating rocks that are older than ten million years
Radio active isotopes are unstable isotopes of an element as there neutron number degenerate by emission of light or medium.

Coal, charcoal, and diamond are not isotopes of carbon; they are forms of carbon but are not considered isotopes. Fluorine is a different element and not related to carbon. Isotopes of carbon include carbon-12, carbon-13, and carbon-14.
Natural chromium is not radioactive. However, there are radioactive isotopes of chromium, such as chromium-51, that are man-made through nuclear reactions. These radioactive isotopes are used in various medical and scientific applications.

Carbon and nitrogen isotopes are not isotopes of each other. They are different elements with their own set of isotopes. Carbon isotopes include carbon-12, carbon-13, and carbon-14, while nitrogen isotopes include nitrogen-14 and nitrogen-15.
