    Aurous is a cation of gold. Gold takes the name "aurum" (Au) with atomic number of 79. In its purest form, the element is bright, slightly yellow, soft, ductile, and malleable. The charge of aurous is + 1. Sulfide, on the other hand, has a charge of - 2.

    Hence, the chemical formula of the compound is Au₂S and its systematic name is gold (I) sulfide.
