First some background...
An element is anything with only one type of atom.
In terms of Chemical structure, any time you see more than one capital letter (like H2O) that automatically it has more than one element, or more than one kind of atom.
So some examples:
H2O (Water)
NaCl (Salt)
C3H8 (Propane)
SiO2 (Sand)
C12H22O11 (Sugar)
