Co2S3 is the formula for cobalt (III) sulfide.
Co2S3 is cobalt(lll) sulfide.
The chemical formula Co2S3 represents cobalt trisulfide. It consists of two cobalt (Co) atoms and three sulfur (S) atoms.
Co2S3also written asCo_2_S_3_sulfide 2- charge trades with the Cobalt 3+ charge
The oxidation number of sulfur (S) in Co2S3 is -2. This is because oxygen (O) usually has an oxidation number of -2 and cobalt (Co) has an oxidation number of +2, so the overall charge of the compound must be neutral, making sulfur's oxidation number -2.
The chemical formula for the compound of cobalt and sulfur is CoS (cobalt monosulfide).
Cobalt (II) selenide has the formula CoSe.
Do you mean Co2S3? If so, that's cobalt (III) sulide. You have to be careful in chemistry in distinguising between upper and lower case letters. CO is carbon monoxide, a compound of the two elements carbon and oxygen. Co is the element cobalt, a metal, Much less likely is CO2S3 which is a complex of carbon disulfide/sulfur dioxide, better written as CS2.SO2.
Some chemical compouds of cobalt are: CoF2, CoF3, CoF4, CoCl2, CoCl3, CoBr2, CoI2, CoF2, CoO, CO2O3, CO3O4, CoS, CoSe, CoTe, CoS2, Co2S3, Co(NO3)2, CoSO4, Co3(PO4)2, etc.
In solid cobalt, metallic bonds are formed between cobalt atoms. Metallic bonds are formed by the sharing of electrons between adjacent atoms, leading to a sea of delocalized electrons that hold the metal atoms together.
