Atoms round out their electric charges by electron exchanges: they can give up, accept, or share these particles to achieve a stable electronic configuration, meaning a lower energy consumption. To emphasize the uncertainty, a diagram showing random motion is more suitable than planetary paths. This theory proposes that the ions of elements on the periodic table fill their last energy levels with 8 electrons. As the electronegativity difference between atoms in a covalent bond increases, electron sharing becomes less even.
