Question

question 9 of 30 what happens to elemental copper when it loses two electrons? a. it is oxidized to cu2-. b. it is reduced to cu2+. c. it is oxidized to cu2+. d. it is reduced to cu2-.

Explanation:

Oxidation is the loss of electrons. When elemental copper (Cu) loses two electrons, it forms a copper - ion with a + 2 charge ($Cu^{2 + }$). This is an oxidation process. Reduction is the gain of electrons, which is not the case here.

Answer:

C. It is oxidized to $Cu^{2+}$
