I need to be able to set up chemical symbols with a subscript and
superscript on the same side of the symbol. Any suggestions about
how this can be done in Word?

Type all the characters on one line (for example HPO42-) followed by a
space. Select the character that should be subscripted (the 4) and press
Ctrl and the = key together. Then select the superscript characters (the 2-)
and press Ctrl, Shift, and = together (or think of it as Ctrl and +).

If you plan to use this symbol often, assign it to an AutoText entry with at
least four characters in its name (so the suggestion tag will pop up when
you type the name). You can store as many symbols as you like.

Some chemists prefer to have the superscript directly above the subscript
instead of having it to the right. This is extra work in Word. You can use
the Equation Editor or tinker with the {Advance} field to move a regular
supercript.
