Electricity put simply is a flow of electrons.
Molecular compounds do not tend to conduct electricity because they have no delocalised electrons and are not free to move and carry electric charge.
Metallic compounds can conduct electricity because they form a lattice where the electrons in the valence shell leave the atom and are free to move throughout the lattice. Therefore a metallic lattice is a whole lot of metal cations (positive ions) as they have lost electrons surrounded by a 'sea of electrons'.
Ionic compounds can also conduct electricity, but not in the solid state. If you dissolve a metal salt such as NaCl into water, it leaves the lattice and breaks down into its constituent ions : Na+ and Cl-. These ions can then move freely throughout the liquid and conduct electric current.
However, acids are covalent compounds that can conduct electricity when dissolved in water, as it ionizes, which means to react with water to produce two or more ions. Electricity put simply is a flow of electrons.

What else can I help you with?
Why are most molecular compound poor conductors?
Molecular compounds are poor conductors because they have no charge. Molecular compounds are simply just covalent bonds. Since covalent compounds dont give or take, they SHARE valence electrons they have no charge. Electricity is only created by positive and negative electrons, but since a molecular compound has no charge they are poor conductors. ONLY MOST ARE POOR CONDUCTORS. Why? Sometimes there is an unbalance and some molecules like Water tend be favor positive or negative, water for instance is just slightly negative.
Compounds with what bonds are poor conductors of electricity even when melted?
Covalent compounds are poor conductors of electricity even when melted because they do not have free-moving charged particles, such as ions or delocalized electrons, to carry an electric current. The strong covalent bonds in these compounds tend to hold the atoms together tightly, preventing the flow of electric charge.
Shows properties of a metal and a nonmetal?
Metals are typically shiny, malleable, ductile, and good conductors of heat and electricity. They tend to lose electrons easily when forming compounds. Nonmetals are generally dull in appearance, brittle, poor conductors of heat and electricity, and gain electrons easily when forming compounds.
Which of the following is a characteristic of nonmetals?
- lower density- lower hardness- lower melting point- lower boiling point- some nonmetals are gaseous or liquidsetc.
Is ionic solutions poor conductors of electricity?
(in short) No, whilst in their solid state ionic crystals are very poor conductors of electricity, however when molten or dissolved their ions are able to carry charge, therefore they are very good conductors of electricity when molten or dissolved in e.g. water. Pure water is a very poor electrical conductor too, it's the dissolved ions that carry the charge.
Why molecular compounds are poor conductors?
molecular compounds are poor conductors because they do not break up into ions. Hope this helps and I'm not to late:)

Are poor conductors of heat poor conductors of electricity?
Yes.
Why is table salt a poor conducter of electricity?
Usually, solid ionic compounds are weak conductors of electricity. Aqueous solutions of ionic compounds are good conductors though as they have free ions for conductivity. When table salt is dissolved, the solution conducts electricity well.
What do you call poor conductors?
Poor conductors of electricity are often referred to as insulators. Insulators have high resistance to the flow of electricity due to their molecular structure, which makes them unable to conduct electricity efficiently. Examples of insulators include rubber, plastic, and glass.
How are the properties of molecular compounds poor conducters of electricity?
Because have lower melting points and boiling points

Are coins good or poor conductors of electricity?
Coins are made of metal and metals are good conductors of electricity.
Is a poor conductors of electricity and heat?
yes

Which set of properties would identify an unknown white solid as a molecular compound?
To identify an unknown white solid as a molecular compound, one could examine its physical properties such as low melting and boiling points compared to ionic compounds, which typically have higher values. Additionally, molecular compounds are usually poor conductors of electricity in solid and liquid states, as they do not contain free-moving ions. Solubility in nonpolar solvents would also suggest a molecular nature, as many molecular compounds are more soluble in organic solvents than in water.
What are materials that are poor conductors of electricity called?
They are insulators.
