Anions attracting electrons

[HydrogenBond]

He is an interesting phenomena. If one looks at an oxygen anion of minus 2, this state implies that oxygen is holding ten electrons while only having eight protons. This implies that something more that electrostatic attraction is occurring.

 

If one runs an electron current in the opposite directions within two wires, the two wires will attract. This is how an electric motor work. Even though the electrons are repelling each other by getting closer their magnetic addition leads to net attraction. Something similar occurs with atomic orbitals allowing the oxygen anion to minimized the electomagnetic force by holding more electrons than protons.

 

Within water the oxygen will lower its electromagntic potential by taking electron density away from the hydrogen. This creates an electromagentic potential within hydrogen. The oxygen is stable and happy with the extra negative charge or else it would not have taken it to begin with. This implies that water, although a dipole, is actually net potentiated on the side of hydrogen.

Try getting an education before dissembling as an educated man. Empty, half-filled, and fully-filled orbitals are especially low in energy. Fe(CO)5 is entirely happy as a molecule, Fe(0); so is Na2Fe(CO)4 , Fe(-2), (Collman's reagent). Na2FeO4 is also a happy camper (Fe(+6), nice purple color). You don't know squat about chemistry.

Actually I am talking about electronegativity. UncleAl, those Fe states are induced because of other highly electronegative atoms; you know because anions will attract electrons up to their stable anion state. In the case of oxygen O-1 wants to become O-2.

 

If we use your example and start with metallic Fe (0) and add O(0) as 02, we first get Fe (+1) and O (-1); leave it long enough, the O(-1) will seek more electron density to become O(-2) and the Fe (+2) to make ferrous oxide. If we go even longer it will form the even more stable Ferric oxide or rust which is Fe (+3) plus O(-2). The magnetic addition allows oxygen to hold more electron density than deduced from pure charge attraction. This puts the burden of needing electrons on the iron. If we take the rust, get rid of all extra oxygen beyond stable rust, and put it in an inert argon atmosphere, grind it to micro size and mixed it will micro size Fe(0) the induced potential on the Fe(+3) will pass on to the Fe (0).

 

In the case of water the oxygen anion is stable and the burden is on the H. In liquid water the only electron density for H to share is from the oxygen of other water. This creates an illusion of balance. This sharing oxygen will try to get some electron density back by taking it out on its own H. If it's own H found some electron density to share ithat H will lose some of that to oxygen, making H need to get closer. This helps make liquid water denser than ice or solid water. The other reason liquid water is denser is that hydrogen bond angles are less than linear in the mobile continuum thereby lowering the amount of sharing available to the hydrogen. This helps oxygen, allowing it to easier remain a stable anion. This results in residual potential for the H.

 

Rust or the oxidation of iron by oxygen is accelerated by water allowing rust to occur at low tempurature. The residual electrophiic potential of the H within water gets the ball rolling by pulling electron density away from the iron making it easier for molecular oxygen to become an anion. Acids increase corrosion by adding extra H potential. Bases will add -OH or hydroxl . This will slow corrosion even though more O2 become solubile, because the extra electron density of -OH lowers the electrophilic potential of the H of water.

Illucid.

[HydrogenBond]

Here is my last example. If we look at Fe and O2 we start with two neutral materials. After exothermic corrosion we will end up with a dipole of Fe+3 and O-2. This dipole formation is exothemic and would appear to defy the laws of physics, if it was not for the exothermic stability of the oxygen anion.
