Scandium's typical oxidation state is +3
Phosphate (PO4) is -3 charge so the formula is:
ScPO4
The molar mass of scandium (Sc) is 44.96 g/mol, while the molar mass of carbonate (CO3) is 60.01 g/mol. When combined in scandium III carbonate (Sc2(CO3)3), the molar mass is calculated as: (244.96) + (360.01) = 233.95 g/mol.
The chemical formula for scandium is Sc and for iodine is I2.
The chemical formula for scandium iodide is ScI3. It is composed of one scandium atom bonded to three iodine atoms.
The formula for scandium III selenide is Sc2Se3. This compound consists of two scandium ions (Sc3+) and three selenide ions (Se2-).
Scandium has the chemical symbol Sc and 21 is it's atomic number. A link is provided to the Wikipedia article on this (usually considered) rare earth element.

Formula: ScCl3
The formula for scandium III selenide is Sc2Se3. This compound consists of two scandium ions (Sc3+) and three selenide ions (Se2-).
Sc2O3
Assuming it's scandium(III), which is its most common valence state, the formula would be Sc2Se3.
Scandium has the chemical symbol Sc and 21 is it's atomic number. A link is provided to the Wikipedia article on this (usually considered) rare earth element.
The compound with the formula Sc(ClO4)3 is called scandium perchlorate. It consists of one scandium atom bonded to three perchlorate ions.
Rb2CO3 for rubidium carbonate
The iodate anion is IO3^-. Scandium is Sc and as III is is Sc^3+. So scandium(III) iodate would be Sc(IO3)3
The formula of sodium [note correct spelling] carbonate is Na2CO3.
