No, it is an ion
Iodide is an ion formed from the element iodine, so it is not a compound.
Rubidium Iodide
Potassium iodide (KI) contain iodine and potassium.
No, iodide is an ion formed by the nonmetal iodine.
In Iodine, the element is in 0 oxidation state, but in Iodide it is in -1. Iodine = I2 , Iodide = I- Iodine can exist freely, but Iodide cannot.
This element is iodine - added as potassium iodide or potassium iodate.
Sn4+ is the symbol for Tin(IV), that is, the element tin with a oxidation state of 4.
The formula of calcium iodide is CaI2. This is because calcium is a group 2 element with a 2+ charge, while iodide is a group 17 element with a 1- charge. Therefore, to balance the charges, two iodide ions are needed for each calcium ion.
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.
Iodide and iodine are not the same. Iodide refers to the ion form of the element iodine, which has a negative charge (I-), while iodine is the element itself in its molecular form (I2). Both are important in various biological and chemical processes.
First, Ag is an element and not a compound at this form. Its name is silver
This element is iodine, added as potassium iodide or potassium iodate.
