What are metallic compounds and why are they conductive?

In the primitive atmosphere, free oxygen was absent. It facilitated the formation of simple organic chemical compounds without loss from oxidstion. Finally, the polymers, essential for primitve life were formed...

Metals are going to be the most conductive on . This is because of , where electrons are free and mobile. It also accounts for a relatively high boiling point....

$"Metallic bonding"$ results from the close packing of metal atoms, such that the atoms contribute a few of their to the overall lattice. These are delocalized, and not associated with...

In order to have a electrical conductivity, you must have free flowing electrons or a "sea of electrons", however, covalent bonds does not have it as it is the sharing...

Take a simple salt such as $NaCl$. We might represent this as $Na^+Cl^-$. Now in the solid state, each cation ($Na^+$) is directly bound to 6 anions ($Cl^-$), and vice...

The generic ionic solid is $MX$, and consists of equal number of $M^+$ and $X^-$ ions that are held together in a non-molecular, electrostatically bound lattice. The ions are not...

And is proposed to be responsible for (i) the malleability (the ability to be beaten into a sheet), and (ii) the ductility (the ability to be drawn into a wire)...

A solid ionic substance is composed of an infinite array of positive and negative ions held together by strong electrostatic forces. The ions are NOT free to move. Once these...

But caesium and mercury are certainly room temperature LIQUIDS. That metals exist in condensed phases under standard conditions is a consequence of , which is a non-molecular force of interaction,...

$"Metallic bonding"$ consists of an array of close-packed metal atoms, which each contribute one or two or more electrons to the overall metallic lattice. And the result is the familiar...
