Homogeneous mixtures are the all the same (homo = same). Heterogeneous mixtures have different parts (hetero = different). Think of it as you could separate heterogeneous mixtures with tweezers, like a Pizza, while silly putty is all together and you cant separate it like that.
Therefore, because Au is the atomic symbol for gold, an element, it must be homogeneous.
Hope this helps!
