Sodium Iodide is held together by covelent bonds, therefore no "free" electrons exist which is what makes metals conductive.

Not in its standard solid state.
Bu aluminum oxide could conduct electricity if molten
Its doesn't have free or mobile electrons as a compound
Aluminium oxide does not conducts electricity because its ions are not free to move / are held in fixed positions (in the lattice).
Yes, to some degree, in the plane of the rings. It doesn't conduct well perpendicular to them.
Coke is the solid carbonaceous material derived from destructive distillation of low-ash, low-sulfur bituminous coal. Cokes from coal are grey, hard, porous, and not considered good at conducting electricity.
All metals Conduct:Tin, steel, iron, copper, aluminum, zinc and all other metals conduct electricity very well compared to most other compounds. (These pure metals conduct, but when they are used to form compounds, the result may of may not conduct electricity.)Why metals conduct:With the discoveries in solid state physics of the 20th century we learned that metals are collections of atoms which have somewhat unusually properties of the electrons. In metals the outermost electron (sometimes two) is not specifically associated with that one atom but is free to associate with atoms far and wide. We say these are delocalized electrons. Since the electrons are not attached to specific atoms, it takes very little energy to move them. As a result, any small voltage causes electron flow in a metal.This movement or flow of electrons is called electricity so this is why metals conduct electricity.Aside: Metals are not the only materials that conduct electricity, they just do it especially well.
Graphite, an allotrope of carbon, is classified as a semimetal, that is, a material that shares some of the properties of metals. Many other non-metallic materials conduct electricity; including salts, plasma and some polymers.
a solid
No, aluminum is definitely in a solid state when it conducts electricity.

Aluminium oxide (Al2O3) is a solid, the oxide of a metal.
Aluminum oxide is a white solid.
Calcium bromide is an ionic solid, in the solid state it does not conduct electricity. Solutions do conduct, as does the melt.
No. Aluminum oxide is a solid. In fact it is one of the hardest known substances.
no.
No. Covalent substances do not conduct electricity in solid or liquid state.
