Is there then the periodic table of elements?

Hi, this is my first post so forgive me if I do it wrong or sound dumb.
I am in a chemistry class and i have to look up if something is a element, which I can do ok at. The other stuff gets alittle confusing for me, Compounds, Solutions, and Heterogeneous mix's.
The things I need to determine what they are vary, Rain Water, Ground Pepper, Window Glass Beach Sand etc..................
Is there a site or table where you can type anything in and get it's physical or chemical properties at for dummys? :lol:
Thanks
