HELP ME/Science Atoms of carbon-14 are radioactive. They decay into
atoms of the element nitrogen. Suppose that a sample of
rock is taken from a fossil. The sample has 1000 atoms of
carbon-14 and 1000 atoms of nitrogen.
If carbon-14 has a half-life of 5700 years, how old is the fossil?
O A. 2850 years old
O B. 17,100 years old
