There are no prefixes in front of the hydrogen, meaning that there is only one hydrogen. Cyanide is the name for the compound CN-. It makes sense that for every one hydrogen atom, there is one cyanide molecule. After all, the hydrogen ion has a charge of +1, and the cyanide ion has a charge of -1. Thus, the chemical formula for Hydrogen Cyanide is HCN, which is neutral.
