Question

Which chemical equation represents the oxidation of lithium (Li) in an electrochemical cell?

A. Li ® Li+1 + 1e–
B. Li ® Li +1 + 2e–
C. Li ® Li+2 + 1e–
D. Li ® Li+2 + 2e–

Answer 1

Answer: I believe the correct answer is A. The chemical equation that represents the oxidation of the lithium ion would be Li = Li+1 + 1e–. In an oxidation reaction, the atom release or donate the valence electrons making an ion and free electrons. For lithium, the valence electron is 1.
