Document Summary
Positron- similar to an electron but instead has a positive charged electron. The beta ray penetrates the 0. 01 mm but not the. 0. 1mm. the gamma ray penetrates even the 100mm. 6- sometimes can damage the cell and if you can somehow kill the damaged cells (cancer) 8- the same element have the same amount of protons or atomic number. The nucleus of a isotope is called a nuclide. 12- transmutation- changing one element into another element= in order for this to happen, the number of protons has to change. 14- the parent and daughter nuclide have the same atomic and mass number. Radioactivity: ionizing, penetrating, high energy and induce phosphorescence. Facts about the nucleus: nuclear and atomic symbols. Nuclear equations: atomic and mass number conservation. Alpha, beta, gamma and positron emission and electron capture. 26-29- write the nuclear equation for positron emission from k-40. First order kinetic rate laws (temperature independent) Rate= deltan/deltat = kn (see ch13, chemical kinetics)
