- Calculate the electrical potential energy of the nucleus if electrons could exist in it.An element of atomic number 83 in a relatively higher energy state decays radioactively to an element of atomic number 84 with lower energy level. This must include an a emission a y emission a ß & y emission a ß emission238 UJess stable than carbon-12 Why is the uranium-238 nucleus nucleus (12 C? Give an explanation by referring to the repulsive coulomb force and the binding energy per nucleon. 92 (Given mass of neutron, m,=1.00867 u ; mass of proton, m,=1.00782 u ; speed of light in vacuum, c=3.00x 10° m st; atomic mass of carbon-12, M=12.00000 u and atomic mass of uranium-238, M=238.05079 u )
- The two nuclei in the nitric oxide (NO) molecule are 0.1154 nm apart. The mass of the most common nitrogen atom is 2.326 * 10-26 kg, and the mass of the most common oxygen atom is 2.656 * 10-26 kg. Find the reduced mass of the NO molecule.Elements that appear in the same column of the periodic table often share similar chemical properties. In the case of the alkaline earth metals, this is troublesome since the body treats calcium (necessary for proper bone growth) and radium (a radioactive element) as chemically similar, storing both in bone marrow. The radium then bombards nearby bone cells with alpha particles, causing them to "crumble." Radium poisoning investigations often center on the identification of radium and its isotopes in bone samples using lonized isotope a mass spectrometer. Pictured is a schematic of a simplified mass spectrometer that shows the paths of calcium isotopes, barium (another alkaline earth metal) isotopes, and radium isotopes entering the chamber. The region shown is immersed in a constant magnetic field of 0.552 T pointing out of the plane of the schematic. Motion of the positively-charged isotopes toward the right was initiated by a potential A -AV- B difference of 3082 V on the two plates…Compute the approximate nuclear radius of: (₂) (c) Palladium-46
- Technetium has not been found in nature. It can be obtained readily as a product of uranium fission in nuclear power plants, however, and is now produced in quantities of many kilograms per year. One medical use relies on the tendency of 99mTc (an excited nuclear state of 99Tc) to concentrate in abnormal heart tissue. Calculate the total activity (in disintegrations per second) caused by the decay of 1.0 mg of 99mTc, which has a half-life of 6.0 hours.Prove using the uncertainty principle that an electron cannot exist inside a nucleus.4) What will be the decay constant for radon with a half-life of 3.82 days?
