“What happens when atoms share electrons?”

Atoms often have free space for electrons in their valence shell, which makes them unstable and prone to reaction. However, is it possible for atoms to share their electrons in order to fill the void? Let’s look at an example. Oxygen has only six of its eight valence electrons occupied, while hydrogen has one out of two. This means that oxygen needs to find a way to retrieve two electrons and the hydrogen needs to find a way to receive one electron. This can be accomplished if two hydrogen atoms shared their electrons with the oxygen atom. Then the oxygen would have it’s valence shell filled and the hydrogen would also. This will for a chemical bond known as a covalent bond. Covalent bonds are completely made up of non-metals, and they are extremely strong and durable, making it very difficult to dissolve a covalent bond.
