    Do you know why in most textbooks, like on http://www.lbl.gov/abc/Basic.html or http://books.google.com/books?id=xD0AwBQECasC&pg=PA196 beta decay equations are written like


    instead of


    Wouldn't the latter be more correct as regards conservation of charge ?

    I usually see it written as

    [itex]^{14}_{6}C\rightarrow^{14}_{7}N+^{ 0}_{-1}e+^{0}_{0}\overline{\nu}_{e}[/itex]

    The equation is discussing the nucleus, not the atom. So no need to put a + in front of the N.

    completely agree with Vanadium..... the + is included in the 7 of Nitrogen
