Ion

Real World Example

Imagine you're at a party, and you've borrowed a jacket from a friend to complete your outfit, making you feel confident and stylish. This situation is similar to how an atom becomes an ion when it gains or loses an electron, changing its charge and properties. Just as borrowing or giving away a piece of clothing can alter your appearance and mood, gaining or losing an electron alters an atom's charge, making it positively or negatively charged, much like how your style at the party changes with the jacket.
