|Water Molecule (H20)|
This is due to the Oxygen atom's electrons being probabilistically pointing towards the Hydrogen covalent bonds. This directs half of it's electrical charge towards the center of the water molecule. Leaving the Oxygen's Protons to positively charge on the opposite side.
The opposite is true for the 'other half' of the water molecule. The positively charged Hydrogen side has it's electrons pointing towards the 'center' of the water molecule creating a negatively charged side of the molecule. Allowing the Protons to positively charge on the opposite end of the covalent bonds.
Both phenomenon are one in the same, because the Protons in the atomic structure of the Hydrogen and Oxygen atoms are not changed. Also note that all stable elements have the same number of Protons as Electrons. Only the electrons are directed toward the center. Thus causing the electrical charges in respect of the shared electron covalent bonds and their protons.
The above mentioned is known as Ionic Bonds between like molecules.
|2D Scalar Waves|
It is best described by looking at the scalar pattern of a Water Molecules color charge patterns on your left. Note the simultaneous attraction and repulsion at the center of the Scalar Wave pattern.
