Carbon exists in three isotopes in nature. Carbon-12 is the most abundant isotope, accounting for 99.8 percent of all carbon ...

Different atoms of the same element are called isotopes. Carbon has three main isotopes. They are carbon-12, carbon-13 and carbon-14. Carbon-12 makes up 99% of an atom, carbon-13 makes up 1% and ...

An isotope is named after the element and the mass number of its atoms. For example, carbon-12 is an isotope of carbon with a mass number of 12.

While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, the number of neutrons defines the isotope of that element ...

It explores the science of carbon isotopes, showing how burning fossil fuels changes the ratio of carbon-12 and carbon-13—clear proof of human-driven climate change. Partnering with Team Trees ...
