The answer is (d). In covalent and ionic bonds the electrons are tightly bound. shiny and hard are qualities most (but not all) metals have but are also shared by non-conducting solids

What kind of bond is formed by delocalized electrons?
Covalent
How do you rank the bond types by increasing delocalization of the valence electrons of least delocalized equals 1 and most delocalized equals 4 A Ionic Metallic B Polar covalent C Pure covalent?
Delocalized electrons are often found in covalently bonded molecules that alternate single and multiple (usually double) bonds. Ranking these 4.1. Ionic2. Metallic3. Polar covalent4. Pure covalent
Out of ionic pure covalent metallic and polar covalent which is most likely to conduct electricity?
All types of covalent compounds are not very good conductors of electricity. However, ionic compounds in their molten state and metallic substances are very good conductors of electricity.
What shares electrons equally?
a nonpolar molecule
Compounds with what bonds are poor conductors of electricity even when melted?
Covalent
A student asserts that silicon and germanium become good insulators at very low temperatures and good conductors at very high temperatures. Do you agree?
silicon and germanium have 4 valence electrons...they will be bound by covalent bonds at very low temperature..hence there will be no delocalized electrons to conduct electricity..therefore at low temperature these two elements behave like insulators....at high temperature,the energy will be sufficient to break the covalent bond and thus electrons become delocalized....therefore at high temp they behave like conductors
What kind of bond is formed by delocalized electrons?
Covalent
Does covalent substances conduct electricity in benzene?
Benzene is nonpolar and thus will only dissolve nonpolar substances. Covalent substances is vague, but even if benzene were to dissolve nonpolar solutes, they would not conduct electricity because the current has no ions or delocalized electrons to travel across.

Which factor distinguishes a metallic bond from an ionic or a covalent bond?
The ionic bond is based on the electrostatic attraction; the covalent bonds involve sharing of electrons.In the metallic bonding the electrons can be considered as delocalized.
What types of bonds do nonconductors of electricity have?
there are two types of bonds that are non-conductors of electricity, ionic bonds and covalent bonds. covalent bonds occur when one or more pairs of electrons are shared by two atoms. ionic bonds are when one or more electrons from one bond are removed and attached to another, resulting in positive and negative ions that attract each other. the main differnece is that non conductors do not have electrons that can move from nucleus to nucleus, so energy cannot be transfered.
What are three materials that are NOT good conductors of electricity?
Nonmetals and covalent compounds are not good conductors of electricity because in these substances no free electrons are present for conductivity
Can tetrachloromethane conduct electricity?
No because it forms covalent bonds and electrons are not free to move in covalent bonds. Therefore, electricity (the flow of electrons) cannot happen. - Ch
