Answer:
It loses electrons.
Step-by-step explanation:
When an atom is oxidized in a redox reaction, it simply loses electrons and the oxidation number increases.
An oxidized atom implies that oxidation has occurred; oxidation can be defined as:
- addition of oxygen to a specie
- removal of hydrogen from a specie
- loss of electron by an atom
- increase in the oxidation number of an atom
- increase in the number of electronegative atoms surrounding an element in changing from reactants to products.
