"oxide" has no formula. An oxide is just a compound (or atom) that has had its valence orbitals satisfied with oxygen molecules. There are a vast number of oxides, each with different formulas.
ie.
Iron (III) Oxide: Fe2O3
Potassium Oxide: K2O
etc.
The formula for tetraiodine octafluoride is IF8.
I4O9 is the chemical formula of tetraiodine nonoxide.
The formula would be I4O9 Iodine is I and the Tetra- means 4 so it is I4 Oxide is of course Oxygen. Oxygen is O and Nona- means 9 so it is O9
P4O10 - P for Phosphorous, 4 for tetra; O for oxygen, 10 for dec-.
Most chemical compound names are taken from what and how many atoms that they are made of. For instance, diphosphorus decoxide is di- (2) phosphorus dec- (10) oxide, or, P2O10.
The formula for tetraiodine octafluoride is IF8.
The chemical formula for fluorine tetraiodine is FI4.

Most chemical compound names are taken from what and how many atoms that they are made of. For instance, diphosphorus decoxide is di- (2) phosphorus dec- (10) oxide, or, P2O10.
The compound name for the formula P4O10 is tetraphosphorus decoxide.
Tetraphosphorous decoxide would be the formal IUAPC name, though P2O5 is the empirical formulation called phosphorous pentoxide, however it is improper to reduce covalent bonds.
The formula for tetraarsenic decoxide is As₄O₁₀. This compound consists of four arsenic atoms bonded to ten oxygen atoms. The prefix "tetra-" indicates the presence of four arsenic atoms, while the suffix "-decoxide" indicates the presence of ten oxygen atoms.
tetraphosphorus decoxide
Tetraiodine nonoxide (I4O9) is a molecular compound. It is composed of non-metal elements (iodine and oxygen) that form covalent bonds to create a discrete molecule.
