    See the link from wikipedia its quite informative -> https://en.wikipedia.org/wiki/Beta_decay
    As the article states for beta decay the mass number remains the same but changes depending on whether its a beta+ or a beta- decay.

    With regards expressions, try find examples similar to the ones given on the wikipedia page.
