What is the nuclear symbol for the radioactive isotope of copper with a mass number of 60?

  • chemistry -

    2960Cu
    The 29 is a subscript before the Cu and the 60 is a superscript before the Cu. I don't have any way to keep the space that shows out of it.

  • chemistry -

    The 29 should sit right under the 60 like this
    60
    29
