However, their full potential has not been fulfilled due to challenges associated with air cathodes and Zn anodes. Webzinc atoms are oxidized to Zn 2+. The half reaction for the oxidation reaction, omitting phase labels, is as follows: Zn → Zn2+ + 2e− This half reaction is balanced in terms of the number of zinc atoms, and it also shows the two electrons that are needed as products to account for the zinc atom losing two negative charges to become a 2+ ion. natural wood teethers
