  1. a. Look on the periodic table. 26 protons and 26 electrons tells you the element is #26.
    b. 53 protons; element #53.
    c. 2 electrons(neutral) so that means 2 protons, also. Element #2.
    d. 20 protons. Element #20.
    e. 0 neutrons. There is only 1 element with no neutrons. It has a mass of 1.
