<u>Answer:</u> When an atom is an ion, it must have a charge.
<u>Explanation:</u>
An ion is formed when a neutral atom looses or gains electrons.
- When an atom looses electrons, it results in the formation of positive ion known as cation. <u>For Example:</u> Sodium looses 1 electron to form ion.
- When an atom gains electrons, it results in the formation of negative ion known as anion. <u>For Example:</u> Chlorine gains 1 electron to form ion.
Hence, when an atom is an ion, it must have a charge.
