    Formula for Barium Fluoride.

    Barium = Ba Fluoride = F

    Look up the charges of numbers of the elements involved .and write them as superscripts to the right of the elemental symbols

    Barium = Ba2+ Fluoride = F-

    'Ba' charge goes to' F' and F charge goes to Ba.

    so its

    BaF2

    The symbol for each element is assigned and found on te periodic table. Compounds have an exact number and kind of elements. The number of each element is given as a subscript.
