2 sulfur 3 oxygen S2O3
If Trioxide refers to Ozonide ion, the formula is O3-
You don't say that. What you do say is that the valency of sulphur in sulphur trioxide is 6.
N2o3
trisulfur septoxide
A sulfone contain the structure S(=O)2-R' where R' is an organic group.
The compound with the formula S2O3 is called disulfur trioxide.
Most formally, the name is disulfur trioxide.
The name tells you the formula. Di- means 2, and tri- means 3, so the formula is S2O3.
The chemical compound sulfur trioxide is known - SO3.
This is a binary covalent compound, so name the less electronegative element first with the greek prefix. The less electronegative element is sulfur and there are two atoms so the first part is disulfur. Next, name the more electronegative element with the greek prefix indicating the number of atoms. This is tetraoxide. So, S2O4 is disulfur tetraoxide.
disulfur trichloride
NaS2 is an unbalanced equation. It would need to be Na2S to be a balanced equation (two sodium, one sulfide). Na2S is Sodium Sulfide.
Disulfur decafluoride is an organic toxic liquid.
penis2 (chloride)
Disulfur heptoxide
The name of S2F10 is disulfur decafluoride.
In one molecule of S2F2, there are 2 atoms of Sulphur and 2 atoms of Flourine making 4 in total.
