Problem: Scientists use carbon dating to determine the age of fossils. 14C is a rare isotope of carbon that has a half life of 5730 years and decays into 14N. By measuring the amount of 14C remaining in a fossil, scientists can estimate when the organism died out to about 60,000 years. The atomic number of C is 6, and of N is 7. 14C and 14N have the same:  a. Atomic number b. Number of protons c. Mass number d. Number of neutrons e. Number of electrons
