How to Insert a Subscript in Microsoft Word

When adding mathematical or chemical equations in Word, use subscripts to make characters much smaller and partially below the rest of the text line. Word converts existing text to subscript or sets subscript as the font type via controls in the Home tab or the Font dialog box.
