If the oxidation number of an atom decreases, the atom has undergone oxidation.
Bumek [7]

Oxidation is a process when an atom, a group of atoms, or an ion loses electrons.

For example,

Cu⁰ -------> Cu⁺² + 2e⁻. This is an oxidation process.

As we can see an oxidation number was 0, and it became +2. The oxidation number is increased. Oxidation number of the atom, when an atom has undergone oxidation, increases.

So, answer is b.False.

Explain how electrically neutral objects can become electrically charged even though charge cannot be created or destroyed.
Nady [450]
Electrically neutral objects can become charged when they gain or lose electric charges. When an object is electrically neutral then the overall charge of the object is Zero. If a neutral object gains negative charges then it will become negatively charged, and if it looses the negative charges (electrons) then it becomes positively charged.
