Hmm... why does the element over there seem so sad... I want to make her feel better.
Oh! Mr. Sodium, it's you! *sighs* It's just that I'm missing one electron and I can't achieve the Octet Rule because of that.
Hey... Why are you crying Ms. Chlorine?
OH MY ION! Thank you so much. I can take because I'm a nonmetal and that way we can both achieve the Octet Rule.
Well... It turns out that I actually have an extra electron. I can give it to you since I'm a metal
Here... Now I will be Cation and you will be an Anion!
YES! Now we are NaCl. We formed an Ionic Bond.
Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the formerly bonded atoms.
