Question

En oxidation state

Answer 1

The question is incomplete. Please specify an element or compound.

Answer 2

The query "En oxidation state" is incomplete. "En" is not a recognized chemical element symbol. To determine an oxidation state, a specific element, ion, or compound must be provided. For example, if the question were about the oxidation state of Oxygen in $H_2O$, it would be -2. If it were about Sodium in $NaCl$, it would be +1. Without this information, a definitive answer cannot be given.
