Question
Which statement is true?
Mg → Mg2+ + 2e–
- Mg gains 2 electrons
- Mg2+ loses 2 electron
- Mg loses 1 electron
- Mg loses 2 electrons
Hint:
Oxidation state increases from 0 to +2.
The correct answer is: Mg2+ loses 2 electron
Oxidation is the loss of electrons during a reaction by a molecule, atom or ion. Oxidation occurs when the oxidation state of a molecule, atom or ion is increased.
Mg → Mg2+ + 2e–
Oxidation state increases from 0 to +2. Mg loses 2 electrons.
