Uranium, an important component of both nuclear weapons and nuclear reactors, has two major isotopes—U-238, which has a half-life of approximately 4.5 billion years, and U-235, which has a half-life of approximately 700 million years. Both were present in equal amounts at the time of the creation of the Earth, 4.5 billion years ago.
How many billion years after the creation of the Earth had the amount of radiation from uranium decayed to half the amount present at the time of the creation of the Earth? (Round your answer to the nearest hundredth of a billion years.)
Carbon-14 (14C) is a radioactive isotope of carbon with a half-life of 5730 years—meaning that half of the 14C in a sample decays into 14N during that time. Suppose a scientist analyzes a sample of ancient plant material from a bog and finds that it contains 1/8th as much 14C as when it formed. Roughly how old is the sample? _____ years
A sample of carbon-14 has a mass of 2.0 × 10–6 g. Carbon-14 has a half-life of 6000 years. How much carbon-14 will be left after 24 000 years?

- The sun’s energy comes from nuclear reactions that fuse lighter nuclei into heavier ones, releasing energy in the process. The solar fusion process begins when two protons (the nuclei of hydrogen atoms) merge to produce a deuterium nucleus. Deuterium is the “heavy” isotope of hydrogen, with a nucleus consisting of a proton and a neutron. To become deuterium, one of the protons that fused has to turn into a neutron. Our interest for now lies not with the nuclear physics but with the conditions that allow fusion to occur. Before two protons can fuse, they must come into contact. However, the energy required to bring two protons into contact is considerable because the electric potential energy of the two protons increases rapidly as they approach each other. Fusion occurs in the core of the sun because the ultra-high temperature there gives the protons the kinetic energy they need to come together. a.
