a.26 electrons,29 neutrons,26 protons
b.53 protons,74neutrons
c.2electrons(neutral atom)
d.20 protons
e.86electrons,125neutrons,82protons(charged atom)
f.0 neutrons

    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.
