Researchers have chemically linked 2D materials using a molecular "velcro," resulting in a device with improved ...

This attraction pulls the atoms together and the electrons are shared by both atoms. The atoms bond because there is a strong enough attraction in both directions and room for the electrons in the ...

So we’d need 2 hydrogens and if each of the two hydrogens shared their electron with one oxygen, two separate covalent bonds are formed and all the atoms in the compound will have full outer shells.

Covalent bonds are strong bonds ... For example Magnesium (Mg) has the electron arrangement 2,8,2. To become stable it must lose its two outer electrons to obtain a full outer energy level.
