P3Cl7 - by the way, I am pretty sure it is classed ans an inorganic compound if that scores extra points for you.
Hope this helps.
P3Br6, (an imaginary compound set as a test I hope!)
The correct formula for sulfur heptachloride is S2Cl7.
The chemical formula for Iodine heptachloride is ICl7.
There is no compound with the formula "P2N8" - it just could not possibly exist.
The prefix tri- means 3 and the prefix tetra- means 4. The prefix is the subscript number for the element in the compound. So the formula for triphosphorus tetrabromide is P3Br4.
