Answer 2

✨Silver Sulfide. Ag2S✨

Silver is a metallic element that typically loses one electron to become a positively charged ion, Ag+1. The sulfur atom needs two electrons to fill its valence electron shell. A valence electron shell is the outermost part of an atom's electron cloud. When a sulfur atom gains two electrons, it becomes a negatively charged ion, S+2. Sulfur can get these two electrons from two silver atoms. After this transfer of electrons occurs, the two ions stick together forming an ionic compound, Ag2S
