- 14C is used in carbon dating of artifacts. Determine the number of protons and neutrons in 14C.arrow_forwardIndicate whether each of the following statements about magnesium isotopes is true or false. a. M1224g has one more proton than M1225g. b. M1224g and M1225g contain the same number of subatomic particles. c. M1224g has one less neutron than M1225g. d. M1224g and M1225g have different mass numbers.arrow_forward2.86 For some uses, the relative abundance of isotopes must be manipulated. For example, a medical technique called boron neutron capture therapy needs a higher fraction of 10B than occurs naturally to achieve its best efficiency. What would happen to the atomic weight of a sample of boron that had been enriched in 10B? Explain your answer in terms of the concept of a weighted average.arrow_forward
