What are the rules for determining oxidation states or numbers?
gpt
1. Uncombined elements have an oxidation number of zero. 2. Compounds have an oxidation number of zero. 3. In a polyatomic ion, the sum of the oxidation numbers is equal to the charge on the ion. 4. In a monoatomic ion, the oxidation number is equal to the charge on the ion.
Explanation: These rules provide a framework for determining the oxidation states of atoms in different chemical contexts, ensuring consistency and accuracy in redox reactions. Understanding these rules is essential for assigning oxidation numbers correctly.
