Answer: The correct answer is it gains electrons.
Step-by-step explanation:
There are 3 subsatomic particles in an atom: Electrons, neutrons and protons.
Neutrons does not carry any charge on them. They are neutral particles.
Protons carry positive charge on them.
Electrons carry negative charge on them.
In an element, number of protons and electrons remains the same.
When an element looses electrons, the number of protons increases than electrons. Thus, the element will have a positive charge.
When an element gains electrons, the number of electrons is more than the number of protons. Thus, the element will have a negative charge.
Hence, the correct answer is it gains electrons.
