Atomic number z - Study guides, Class notes & Summaries

what makes a material conductive - ANSWER Reasoning for conductivity: delocalized 'sea' of electrons loosely bonding the layers together. These delocalized electrons can all move along together - making graphite a good electrical conductor. atomic number - ANSWER Z the number of protons in the nucleus of an atom atomic mass unit - ANSWER a unit of mass that describes the mass of an atom or molecule measured in amu

Elsevier Adaptive Quizzes A radiologic technologist is working on barium and iodine. Which term does the radiologic technologist use to refer to 134/56 Ba and 131/53 I ? a. Isobar b. Isomer c. Isotope d. Isotone - d. Isotone Isotones differ in their atomic numbers and mass numbers, but they have the same number of neutrons, that is, a constant for the quantity a (atomic number) - z (mass number) a-z. Types of ionizing radiation used in various techniques have different ranges of...
