Why are covalent compounds not 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...

The reason as to why metallic posses these properties is because the electrons do not stay in their assigned orbitals, they become delocalised and move all over the place....

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...

Covalent molecules are two non-metal atoms that share their to complete their outer shell. For example, Hydrochloric Acid (HCl). Generally, Covalent molecules also have different properties to like low melting...

Ionic bonds are created by electrochemical attraction between atoms of opposite charges, while molecular bonds (aka covalent bonds) are created by atoms sharing electrons in order to complete the rule...
