Diffusion is the net movement from an area of higher concentration to an area of lower concentration. The mechanism by which this happens is the random molecular motion: the right answer is " <span>Diffusion is
the movement of molecules from an area of lower concentration to one of
higher concentration by random molecular motion"</span>
<span>The attraction between the shared electrons
and the nuclei that holds the molecules together in the second energy level of
phosphorus atom is a covalent bond. Electrons are kept in the orbit around the
nucleus by the electromagnetic force and the protons in the nucleus are held in
place by the strong nuclear force, which overcomes the electromagnetic
repulsion.</span>
