Each chemical element has a different chemical symbol formed from one or two letters: H for hydrogen, U for uranium, Cl for chlorine, Ar for argon, etc. Symbols are used for simplicity in writing equations, etc. The chemical symbol can be considered as a code.
Delta as a mathematical symbol usually means "change". It's usually used the same way in physics and chemistry, though it's sometimes used in chemical equations to represent heat.

In Microsoft Word, chemical equations can be entered using special character menus. For example, subscripts and superscripts can be used to denote isotopes, and arrows can indicate reactions.
Because they are shorter.
