Roughly, the iodide ion appears as shown below:
.. -
:I:
..
The symbol for the potassium ion is K+ and the symbol for the iodide ion is I-. When potassium iodide (KI) forms an ionic compound, the potassium ion (K+) and the iodide ion (I-) combine in a 1:1 ratio to create KI.
Iodide is iodine with a negative charge, and is thus written as I-.
No, iodide is an ion formed by the nonmetal iodine.
The formula for ammonium iodide is NH4I. It is composed of one ammonium ion (NH4+) and one iodide ion (I-).
The symbol for Hydrogen iodide is HI.
The symbol for the potassium ion is K+ and the symbol for the iodide ion is I-. When potassium iodide (KI) forms an ionic compound, the potassium ion (K+) and the iodide ion (I-) combine in a 1:1 ratio to create KI.
The Lewis symbol for a magnesium ion (Mg^2+) would consist of the symbol "Mg" with a 2+ charge shown as two dots next to the symbol to represent the loss of two electrons from the neutral magnesium atom.
The Lewis symbol for a cesium ion (Cs+) is Cs with a superscript showing a positive charge (+) and no dots around the symbol, indicating that the ion has lost one electron to achieve a fully stable electronic configuration.
Iodide ion : I-
No, potassium iodide is a compound composed of the monatomic ion K+ (potassium cation) and the monatomic ion I- (iodide anion). It is not a polyatomic ion.
Iodide is iodine with a negative charge, and is thus written as I-.
iodine and iron
No, iodide is an ion formed by the nonmetal iodine.
The symbol for Hydrogen iodide is HI.
The formula for ammonium iodide is NH4I. It is composed of one ammonium ion (NH4+) and one iodide ion (I-).
Ammonium Iodide
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.
