  1. Tough to do subscripts and superscripts so the left number is the atomic number and the right number is the mass number. Just make mass numbers add up on both sides and atomic numbers add up on both sides.
    86Rn222 ==> -1e0 + 87X222
    Then you look up X on the periodic table. What is 87? It's Fr so replace the X with Fr and you have it. Now you do the alpha decay. Look up CANDU on the web.
