When you say chemicals, I assume you mean elements? 

Sort of in order of diminishing abundance:

O, Si, Al, Na, K, Ca, Fe, Mg- then potentially a whole host of minor elements.

Hopefully this is what you were looking for?

Maybe you are looking for the most common minerals in granite. If so, they are plagioclase and alkali feldspars and quartz. Others may also be present though and are primarily amphiboles, biotite micas, pyroxene, apatite, tourmaline, sphene, beryl, augite, zircons, garnet, topaz, cordierite, fayalite, titanite, and possibly some rare earth oxides.
