If I am not mistaken cyanide can be several specific compounds and is usually one carbon atom triple-bonded to three nitrogen atoms. I doubt that one would hardly ever find cyanide in an ionized state.
Ferrocyanide carries the negative charge in the form of the ferrocyanide ion, which is [Fe(CN)6]4-. This ion consists of a central iron atom (Fe) surrounded by six cyanide ions (CN-) that act as ligands. The overall charge of the ion is negative, with the cyanide ions providing the negative charge.
The two common polyatomic ions whose names end in -ide are the cyanide ion (CN-) and the hydride ion (H-).
Fe(CN)₂ is composed of iron (Fe) ions and cyanide (CN) ions. In this compound, iron typically has a +2 oxidation state, making it a ferrous ion (Fe²⁺), while each cyanide ion carries a -1 charge. Therefore, the overall structure consists of one Fe²⁺ ion and two CN⁻ ions.
This is the electrical charge of the ion.
Isoelectronic species are atoms or ions that have the same number of electrons. The azide ion (N₃⁻) has a total of 10 electrons (7 from nitrogen and 3 from the extra negative charge). Isoelectronic species with the azide ion include the nitrite ion (NO₂⁻) and the cyanide ion (CN⁻), both of which also have 10 electrons.
The charge on the polytomic ion cyanide is -1.

One potassium ion will be needed to balance one cyanide ion because potassium has a +1 charge and cyanide has a -1 charge.

The cyanide ion (CN-) has the same charge as the hydroxide ion (-1).
Hydrogen cyanide is an anion so it is a negatively charged ion.
It is the cyanide ion. There should be a single negative charge on it
Nitrate (NO3^-), because the Hydroxide ion also has a negative one charge (OH^-)
Ferrocyanide carries the negative charge in the form of the ferrocyanide ion, which is [Fe(CN)6]4-. This ion consists of a central iron atom (Fe) surrounded by six cyanide ions (CN-) that act as ligands. The overall charge of the ion is negative, with the cyanide ions providing the negative charge.
The oxidation number of Ag in Ag(CN)2- is +1. This is because the overall charge of the complex ion is -1, and each cyanide ion (CN-) has a charge of -1. Since there are two cyanide ions, the total negative charge is -2, leaving the silver ion with a +1 oxidation state to balance the charge.
The ionic formula for sodium cyanide is NaCN. Sodium is a group 1 metal that forms a +1 cation, and cyanide is a polyatomic ion with a -1 charge. Therefore, one sodium ion (Na+) combines with one cyanide ion (CN-) to form the compound NaCN.
The oxidation number of the nitrogen atom in the cyanide ion (CN-) is -3. This is because carbon is more electronegative than nitrogen, so it takes the -1 oxidation state while nitrogen takes the -3 oxidation state to balance the overall charge of the ion.
