It is ScI3.
When scandium reacts with iodine, it will form the ionic compound scandium(III) iodide, with the formula ScI3. Scandium typically forms ionic compounds in which it loses its 3 valence electrons to achieve a stable octet configuration.
The chemical formula for scandium is Sc and for iodine is I2.
BaI2 is the chemical formula for Barium Iodide.
Formula: AuI
Formula: NaI

The formula for hydrogen iodide is HI.
Formula: NaI
Scandium's typical oxidation state is +3 Phosphate (PO4) is -3 charge so the formula is: ScPO4
Only Scandium iodide (or if you want scandium triiodide), ScI3.
Mercury(I) iodide (HgI2) is the chemical formula for solid mercury iodide.
The formula for scandium III selenide is Sc2Se3. This compound consists of two scandium ions (Sc3+) and three selenide ions (Se2-).
