Radon 104 Questions and Answers with Complete Solutions

Radon 104 Questions and Answers with Complete Solutions for most elements, the number of neutrons in the nucleus is? greater than the number of protons the number of protons and neutrons in the nucleus is known as? the Mass number the nucleus of an atom contains approx._________% of atomic mass 95% when the nucleus is formed, a certain amount of mass is destroyed and converted to energy called nuclear glue, the binding energy of the nucleus. in photodisintegration a very high energy photon interacts with a nucleus and the most likely probability is that a neutron may be released the rest mass of an electron is .511 Mev isotopes have the same number of protons in photodisintegration, a photon is absorbed by the nucleus and a nucleon is usually emitted by that nucleus. True Internal "pair production" is associated with beta positive decay Radioisotope Yz decays by alpha decay. in the process the total energy KE of the alpha particle. every time a Yz nucleus decays the KE of the alpha particle will be the same. True Radioisotope Nz decays by beta negative decay. in the process, the total energy is the KE of the beta particle. every time an Nz nucleus decays the KE of the beta particle will be the same. False Radioisotope Tz decays to Cz by electron capture. Tz could also decay to Cz by which process? Beta positive Both beta-positive and beta negative decay results in a range of beta particle energies up to a maximum energy True A radioisotope emits a 2 Mev gamma ray and a 4 MeV alpha particle. the appropriate shielding from a radioisotope is determined by the higher of the two energies. False. The appropriate shielding is determined by the quality of the radiation. the rate of decay of a radioisotope is also referred to as Activity The type of equilibrium that is used for milking such as Mo and Tc is called Transient equilibrium Electron capture results in the production of characteristic x-ray true How many protons/neutrons in the nucleus of 14/6C? 6 protons 8 neutrons what force holds protons and neutrons together in a nucleus. strong force what type of nuclear decay most often produces the greatest mass loss. alpha decay what fraction of a radioactive sample has decayed after two half-lives have elapsed 3/4 a sample of organic material is found to contain 18g of carbon-14. based of samples of pottery found at a dig, investigators believed the material is about 23000 years old. the half-life of carbon-14 is 5715 years. estimate what percentage of
