I’m making some revision sheets and I need to know how to write in superscript and subscript.
Also, I need to know how to write the chemical symbol. For example, Hydrogen would be H with a superscript 1 and a subscript 1 directly above each other. Know what I mean?
Like in the Periodic table.
All answers appreciated. 
Use the equation editor.
Office 2003: Insert > Object > Microsoft Equation
(a toolbar should apper with all the suscript and superscripts that you need)
Office 2007: Click where you want to insert the equation.
On the Insert menu, click Object, and then click the Create New tab.
In the Object type box, click Microsoft Equation 3.0.
If Microsoft Equation Editor is not available, you may need to install it.
If you need help, click Equation Editor Help Topics on the Help menu.
in ms word, go to the “insert” tab, press
“object”, there you would find microsoft equation 3.0,press on it and a toolbar appears, and u’d find all sorts of equation writing stuffs from a to z there…evrythn related to equation is there…..but if u dnt hv microsoft equation 3.0 in
“objects” u may need to install it from your microsoft office cd…HOPE IT HELPS
Subscripts and superscripts are very much available in the fonts menu. There is a set of symbols with which = or gives to can be typed. But using the sub/super scripts is very tiring. You are right if a special scientific menu is given by Microsoft.
A short cut for wrting sub scrips is to press ctrl and = then just type what you want for super scripts press ctrl shift and =
