Question

.What is the minimum oxidation state of metals ?​

Answer 1

Answer:

The oxidation state of a pure element is always zero. The oxidation state for a pure ion is equivalent to its ionic charge. In general, hydrogen has an oxidation state of +1, while oxygen has an oxidation state of -2. The sum of the oxidation states for all atoms of a neutral molecule must add up to zero.
