Answer: The correct answer is Option c.
Step-by-step explanation:
Ions are formed when an atom looses or gains electrons.
If an atom gains electrons, it leads to the formation of negative ions known as anions. For Example: Fluorine gains 1 electron to form
ions.
If an atom looses electrons, it leads to the formation of positive ions known as cations. For Example: Sodium looses 1 electron to form
ions.
Hence, the correct answer is Option c.
