Well...yes and no.
It's important to understand what sulfide is. The "ide" suffix means the atom has a negative charge on it, basically. Same with hydride, H-. Or the halides, fluoride, chloride, bromide, iodide - F-, Cl-, Br-, I-.
It's an anion. So what is Sulphide? Well it's S-. Actually it's S2- with 2 negative charges.
Which nicely demonstrates something else about "ides", that they are usually the lowest common oxidation state of the element. You can often tell what that is by inspection but otherwise, just Google it.
Anyhow, so now we know sulfide is s2-. It's not really a liquid because...it's not really anything. It just exists in things. You're not going to see it just lying around and you're not going to observe it alone outside of some pretty harsh conditions.
It is a liquid in the sense that it may form in a liquid! If we have H2S (hydrogen sulfide! Note the ide in the name. Each hydrogen is H+ so the S is 2-...it's a sulfide even while part of a compound.) and manage to pluck off both hydrogens then, yea, we'll have sulfide floating around in the solution....albeit in an extremely impure state.
In conclusion, the name sulfide basically means sulfur and then describes that sulfur a little bit. It's S2-, whether part of a compound or not....whether a liquid, solid, gas, whatever.
Lead is a solid at room temperature. It has a melting point of 327.5°C and a boiling point of 1749°C.
lead(II) sulfide Sulfur has an oxidation number of 2. Cross then superscript S^2 down in front of lead and there ya go.
No, Lead Sulfide (galena) is a brittle crystalline solid with semiconducting properties.
No, it is a solid.
It would be a solid at room temperature and standard atmospheric pressure.
Yes, lead sulfide is a solid compound at room temperature and pressure. It is insoluble in water and has a dark gray color.

The lead acetate test is used to detect the presence of sulfides in a sample. This test results in the formation of a black precipitate of lead sulfide (PbS) when lead acetate is added to a solution containing sulfide ions. Lead sulfide is insoluble and appears as a dark-colored solid.
The wood is solid but the lead can be crushed into finite pieces. the lead is still solid eventhough it behaves like a liquid as the atom of the crushed lead is aranged like a solid.
Lead(II) Sulfide = PbS Lead(IV) Sulfide = PbS2
Lead IV Sulfide is PbS2
solid
Lead Sulfide is PbS.
Lead sulfide is a black solution. It is insoluble in water and is a precipitate. The principle of the lead acetate test is the formation of lead sulfide.
Lead is a solid at room temperature. It has a melting point of 327.5°C and a boiling point of 1749°C.
