What is a CN polyatomic ion?

The CN polyatomic ion is a polyatomic ion in the cyanide family. Many polyatomic ions occur in families, meaning they share the same central atom and carry the same charge. Other members of the cyanide family include cyanate and thiocyanate.

When looking at polyatomic ion families, there are a few generalizations that can be made. Different members of the family can have different numbers of oxygen. Family members can combine with hydrogen ions to partially neutralize their negative charge. Some family members can substitute sulfur for oxygen. In general chemistry, polyatomic ions encountered most frequently are ammonium, hydronium and mercury (l).
