Iodide (I-) ion
the charge on that ion
Negative 2.
the charge on that ion
The charge. Cations and anions have an oxidation number equal to their charge, for example in Fe2+, Fe hasan oxidation number of +2 and in S2- S has an oxidation number of -2. Uncharged atoms have zero oxidation number.
It is equal to the charge. Oxidation number depends on charge.
In most cases it is the value of its charge, but not always.
Molecular formula represents the actual number of atoms of different elements that constitute the molecule.
Oxidation Number
Yes. it is
Calcium forms a 2+ ion.
Iodide (I-) ion
the charge on that ion
No, it is a salt made of 1 Ca2+ ion and 2 Cl- ions with no total net charge. Hope this helps
