Question

Which of the following processes would be considered oxidation?

1) Addition of hydrogen
2) Gain of electrons
3) Loss of electrons
4) Lowering of charge
5) Loss of oxygen

Answer 1

Oxidation is characterized by the loss of electrons, gain of oxygen, or loss of hydrogen, and therefore, in the choices provided, the loss of electrons is the correct answer. The correct option is 3.

Step-by-step explanation:

Among the options provided, the process that would be considered oxidation is the loss of electrons. Oxidation can be defined in several ways, including the complete loss of electrons from a molecule or atom. In terms of molecular changes, oxidation may also involve the gain of oxygen or the loss of hydrogen.

Therefore, the use of the word oxidation can be appropriate in various contexts, such as ionic reactions, organic reactions, and changes in oxidation numbers. The correct option is 3.
