It must be "a"
Sulfide is a sulfur ion with -2 charge.
copper sulfide
Aluminum sulfide
Ag2S = silver sulfide
calcium sulfide :))
No. Sulfide is simply a sulfur atom with a negative charge. To be organic a compound must contain carbon.
Sulfide is a sulfur ion with -2 charge.
Yes, it is a compound of hydrogen and sulfur, or sulfur dioxide.
Sulfur is an element. Sulfide, the ion formed by sulfur cannot exist on its own as a substance because it carries a negative charge and must be accompanied by a positive ion.
Gallium has a number of sulfides Ga2S, [Ga+]2 S2- (gallium(I) sulfide) GaS, [Ga24+] [S2-]2 gallium (II) sulfide Ga4S5 - undocumented structure so simply call it tetragallium pentasulfide Ga2S3, [Ga3+]2 [S2-]3 gallium(III) sulfide These compounds all have a large degree of covalent character in their bonding so expressing them as ionic substances is only a useful formalism to understand the oxidation states of the metal.
