Drawings of covalent bonds. Polarity
Firstly ( 1 ) we see the nucleus of an atom in static state, to check so, as the gravitational and magnetic lines should be without rotation.
Second ( 2 and 3 ) you can see this nucleus in rotation and as so much gravitational lines as magnetic ones are deformed in spiral way. Also we see as the orbital cuts take place (distances in which orbits are placed). Also ( 4 ) we can see the atom with all ist orbits built on the orbit cuts.
Later ( 5 and 6 ) we can see the atom already constituted, with its North-south magnetic direction, which atoms use so much for their molecular alignment as for their crystalline alignment.
Then ( 6 ) we have an atom (lithium) with its eletrons in rotation in the same sense as its nucleus has (spin). Also the magnetic lines that envelop atom, which represent the orbital cuts in all the sphere positions and the resultant polarity N-S.
And finally ( 7 ) we observe as a molecule of flourine should be formed when their polarity N-S attract their atoms. In the same way a Binary star should be formed.
