As one of the environmental isotopes, it makes up about 1.1% of all natural carbon on Earth. Carbon-13, 13C. General. Symbol, 13C.

There exist two stable carbon isotopes in the natural world: 12C and 13C. The abundance ratio of 13C is about 1% of 12C.

While only approximately 1% of all carbon on Earth is of the 13C isotopic form, 14C is still much rarer. Only one out of every trillion carbon atoms is 14C.

This table shows information about naturally occuring isotopes, their atomic masses, their natural abundances, their nuclear spins, and their magnetic moments.
