ZnI2
Zinc has a +2 charge and Iodine has a -1 charge. It takes 2 Iodine to balance on Zinc.
As an element iodine is 'I2' and calcium is 'Ca'. However, in combination it CaI2 ( Calcium Iodide.
The chemical formula for the compound formed between iron(III) and iodine is FeI3 (iron(iii) iodide).
KI or potassium iodide. See the related link for more information.
No, iodide is an ion formed by the nonmetal iodine.
This compound is iron(II) iodide - FeI2.
The only iron iodide listed in the Handbook of Chemistry and Physics (1985) is iron (II) iodide, with the formula FeI2 Hypothetically, there could be an iron (III) iodide with the formula FeI3, but this probably spontaneously transforms into iron (II) iodide and elemental iodine.
