Bonds what is ionic vs. Covalent? |
Atoms that lose or gain electrons become electrically charged which those atoms are called ions. Ionic bonds form between oppositely charged ions. Covalent bond is two atoms share one outer shell electrons and they are the strongest. They hold together a molecule. They form equal to the number electrons to fill it's outer shell. |
