Iodine and hydrogen have a valence of 1- and both exist naturally as diatomic molecules.
ie: I2 and H2 (most commonly iodine gas and hydrogen gas respectively)
Therefore the formula is:
HI
The formula for hydrogen iodide is HI.
The chemical formula for ammonium iodide is NH4I.
The formula for hydrogen iodide is HI. It is a binary compound made up of hydrogen and iodine atoms.
The chemical formula for potassium iodide is KI.
Iron(II) Iodide = FeI2 Iron(III) Iodide = FeI3
Formula: HI
Hydrogen iodide, or, in water solution, hydriotic acid
There is no 'binary formula'. You can say that hydrogen iodide is a binary compound, that is one formed from just two elements. HI is its formula.
The formula for hydrogen iodide is HI.
HI, written with no spaces, is the chemical formula for a compound named "hydrogen iodide" [not "hydrogen iodine" as written in the question.]
The compound formed when hydrogen and iodine join together is hydrogen iodide, which has the chemical formula HI.
MgI2 is the chemical formula of magnesium diiodide, a salt; an acid is hydrogen iodide, HI.
Formula: NI3
The chemical formula for ammonium iodide is NH4I.
The chemical formula for antimony iodide is SbI3.
The formula for hydrogen iodide is HI. It is a binary compound made up of hydrogen and iodine atoms.
The chemical formula for monatomic iodide is I-.
