We know there are high temperature superconductors of the copper
compounds. We know there are low temperature superconductors of pure
elements such as mercury or lead.

So, if the true theory of Superconduction is one of Maximal Conduction
Bands and of Maximal Electronegativity/Electropositivity then one
would
expect that these comprise one and the same phenomenon.

In the metallic bond where electrons form a sea of electrons in loose
association giving rise to metallic characteristics of ductile,
malleable, current carrying. Can we craft that Conduction Band theory
to
be the same as the Electronegativity/Electropositivity theory?? Can
those two different theories be conjoined to be the same theory?

I believe so. Consider that the electronegativity of fluorine and
electropositivity of cesium in the push of cesium to give up an
electron
and the pull of fluorine to acquire an electron constitutes an
"electron
conduction band". And consider the purified silver wire with its sea
of
electrons in the metallic bond, can we not see that electrons in the
metallic bond have pushes and pulls much the same as if
electropositive
and electronegative sources.

So, can we combine Conduction Band theory and Electronegativity theory
as one theory and say that by splitting them we are merely making a
convenience, but that they are fundamentally one and the same concept.

So that if we can combine the two into one, then low temperature
superconductivity of pure elements such as mercury or lead involve the
Conduction Band arrangement whereas the high temperature
superconductors
of the copper compounds, cuprates involve more of the
Electronegativity/Electropositivity.

As for the Meissner Effect of the exclusion of a magnetic field, I
wonder if that is connected to the idea that the "point of
superconduction" is the point at which the material creates a "Self
Current". In a different post I asked if anyone has ever noticed a
tiny
milliampere current from the act of simply lowering the temperature of
a
cuprate. Where the self created current is superconductivity and thus
when an outside current is applied that there is no resistance. If a
material is creating its own current then an outside added current
would
show no resistance.

Another Experimental Test: Has anyone noticed in superconduction
whether
the current ever exceeds the applied current? Example: let us say we
apply 1.1 amperes to a superconductor, and the reading registers 1.2
amperes. And the explanation would then be that the self-created
current
plus the applied current is what is registered.

Not explained: what is not explained is why silver and copper with
their
highest normal conductors, why these two elements have such a low
temperature superconduction Tc considering that their Conduction Band
is
so highly conducive. One would think that the highest normal conductor
would just blend in easily and superconduct at high temperature.

Possible explanation: sure silver and gold and copper are the highest
normal conductors of electricity due to Conduction Band, but because
superconduction is the arrangement of atoms where the push and pull of
electrons creates a self internal current just by the lowering of the
temperature, then silver gold and copper have to back-track in its
geometry to get to this special arrangement of push and pull.

More later ...

I don't think Energy bands remain the same when the temperatures go
down. Also does it make sense to regard electronegativity as a cause
since we're talking about elemental species ?

My point was that given a solo elemental species such as gold, that
you can
take the Conduction Bands of gold and get Electronegativity and
Electropositivity. Gold is metallic bonding with a sea of electrons
and
what moves a specific electron in gold is a push or a pull. So the
metallic
bond is another form of Electronegativity and Electropositivity.

Reversing the situation and take a solution of Na and Cl in water. Can
this
be analyzed as a metallic bonding with a sea of electrons. I say yes.
I say
that all of these chemical bondings:

polar bonds
covalent bonds
ionic bonds
metallic bonds
etc etc etc

are mere inventions for "convenience sake to chemists" (perhaps lazy
chemists)
who seem to never want to organize and clean up their house of "bonds"

What can unify all the bonds of Chemistry? Perhaps the answer is push
and
pull.
I call these pushes and pulls as electropositivity and
electronegativity.

So how is the Na with Cl in water a metallic bonding and thus a
Conduction
Band? It is because each electron if it moves has a push or pull or
both
associated with it. And the Conduction Band of Na, Cl in water is an
instant snapshot of the electrons in motion.

Bonds in chemistry had no reality, but was mere classification. The
reality
is that an electron that moves in a medium moves because of a push or
pull.

Normal Conductivity-- that is when there is a high degree of electron
motion and also resistance

Superconductivity-- that is when the Electronegativity and
Electropositivity of pull and push are so maximized that the material
is at
the threshold of creating a self-current from the mere fact of the
cold
temperature lowering. In such a condition that when a external current
is
applied, since the electrons are at the verge or threshold of a
spontaneous
self current that the external current flows with no resistance
whatsoever.
The metaphor of the England roads that superconduct cars is apt, in
that
there are boom arms alongside the road that spank each car that passes
by
or pulls a car coming towards and imparting a acceleration to the car.

I never liked the silly classification scheme in Chemistry where they
sit
around dreaming up thousands of new "bonds". They are worse then
biologists
have have nothing better to do than to make pigeonhole boxes of new
terms
that have no reality.

All bonds in chemistry have two things in common-- push and pull of
electrons and nuclei. So is the metallic bond in gold with Conduction
Bands
really any different from Na, Cl in water? No, because both have only
one
thing making it happen-- electron push and nuclei pull.

So we can dispense with chatter of covalent bond or ionic bond and
focus on
the one aspect of push and pull.
