1. Could lead-214 undergo an alpha decay to become mercury-210? The atomic masses are as(1 point)follows: for 21482Pb, , 213.9998054 u; for 219H,"golg, , 209.99451 u; and for 4He, , 4.002603 u.OYes, because the parent nucleus has more mass than the daughter nucleus by itself.OYes, because the parent nucleus has more mass than the daughter nucleus and alpha particle.ONo, because the parent nucleus has approximately the same mass as the daughter nucleus and alpha particle.ONo, because the daughter nucleus is an unstable isotope.2. Which property signifies a nucleus that is likely to undergo beta decay? (1 point)Oa very low neutron-to-proton ratioOa mass number greater than 209Oa very high neutron-to-proton ratioOan atomic number greater than 833. Dinosaur fossils are over 65 million years old. If some carbon from the dinosaur's body(1 point)remained in the fossil, would radiocarbon dating be useful for determining the age of thefossil?ONo, the carbon would have bonded chemically with other elements.Yes, radiocarbon dating is useful for carbon-containing specimens of any age.ONo, too much of the carbon-14 would have decayed for radiation to be detected.
