What is the relationship between the sum of oxidation numbers of atoms in a polyatomic ion and its charge?
gpt
The sum of oxidation numbers of atoms in a polyatomic ion equals its charge.
Explanation: The charge of a polyatomic ion is determined by the sum of the oxidation numbers of all the atoms in the ion. This relationship allows chemists to calculate the charge of a polyatomic ion based on the oxidation numbers of its constituent atoms.
