Ion notation

  1. Aug 28, 2010 #1
    I've seen ions notated with the postive or negative sign both before and after the element name (usually after). Is this just preference or does its placement indicate anything?

    Interesting. My textbook seems to use them interchangeably for some reason.

    Some books will flip the order in which A and Z are displaced (that was the case of my first chemistry textbook).

    But I have never found a textbook indicating charges in the "wrong" side. Perhaps it's just an old notation that has since disappeared.
