Question

Responses

the ratio of protons to neutrons in carbon-14
the ratio of protons to neutrons in carbon-14

the difference between the amounts of carbon-12 and carbon-14
the difference between the amounts of carbon-12 and carbon-14

the ratio of carbon-12 to carbon-14
the ratio of carbon-12 to carbon-14

the difference between the number of protons and neutrons in carbon-14
the difference between the number of protons and neutrons in carbon-14

Answer 1

The correct response is:

the ratio of carbon-12 to carbon-14

This ratio is used in radiocarbon dating to determine the absolute age of organic materials, since carbon-14 decays over time.
