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 Answer 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 penetrability into the sk...

Rutherford's Gold Foil Experiment - correct answer proposed that atoms consist of a tiny, massive, positive nucleus surrounded by electrons nucleus - correct answer contains all the positive charge and nearly all the mass of the atom James Chadwick - correct answer discovered the neutron cathode rays - correct answer move from negative electrode to positive electrode (like electrons in a voltaic cell) Thompson's Cathode Ray Experiment - correct answer discovery of the ele...
