Which of the four fundamental forces of nature is responsible for joining atoms together to form molecules?

Answer 1

None.

When an element needs or has too many electrons, it forms molecules. For instance, oxygen is usually found in nature as 02. Other molecules are created through chemical reactions, such as when gasoline burns, which produces carbon dioxide and water as its two main byproducts.

When two hydrogen atoms are placed next to each other, they will share electrons to fill the first energy level that an atom needs to be stable because hydrogen atoms only have one electron, which makes them unstable.
