why are ionic compounds conduct electricity?
31727
Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.

Ionic compounds are held together by electrostatic forces between the oppositely charged ions . These forces are usually referred to as ionic bonding .

Ionic compounds consist of oppositely charged ions that are held together by ionic bonds. ... Ionic compounds are solids with high melting and boiling points. They are good conductors of electricity but only when dissolved in water. Their crystals are rigid and brittle.

High melting and boiling points - Ionic bonds are very strong - a lot of energy is needed to break them. So ionic compounds have high melting and boiling points. Conductive when liquid - Ions are charged particles, but ionic compounds can only conduct electricity if their ions are free to move.

All ionic compounds are polar. This is because ionic compounds consist of ions of opposite charges held together by electrostatic forces of attraction. Thus in ionic compounds, the positive and negative charges are present separately, because of which all ionic compounds will be polar.

Covalent Compounds Are Poor Conductors They also conduct heat very well because the ions are all right next to each other, making it possible for energy to be transferred efficiently from one place to another. Covalent compounds, on the other hand, are almost always good insulators of both electricity and heat.

Generally, ionic compounds are better conductors of heat (and electricity) when in molten form or when dissolved in the water. ... In the case of ionic compounds, in the molten state or when dissolved in water, free carriers (electrons) are available for conducting heat.

Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move. Ionic compounds are conductors of electricity when molten or in solution, and insulators when solid.

When solid, ionic compounds do not conduct electricity as the ions are held in fixed positions and cannot move; however, when molten or dissolved in water the lattice breaks down and the ions can move and carry charge. Therefore, ionic compounds can conduct electricity when molten or dissolved in water.

The compound is ionic in nature, because it contains a metal (aluminum) and a non-metal (oxygen). Ionic compounds occur between metals and non-metals and involve the exchange of electrons between the two atoms. The metal always donates electrons to the non-metal to form the ionic bond.

One or more electrons are transferred from a metal atom to a nonmetal atom to form ions. Ionic bonds are the electrostatic attractions between positive and negative ions. An ionic compound is a three-dimensional network of alternating cations and anions that are mutually attracted to one another.

Giant ionic structures. The ions in a compound , such as sodium chloride, are arranged in a giant ionic structure (also known as a giant ionic lattice). ... This means that ionic compounds have high melting points and boiling points. Solid ionic compounds do not conduct electricity because the ions are held firmly in place ...

The particles in an ionic compound are held together because there are oppositely charged particles that are attracted to one another. ... are hard because particles cannot easily slide past one another. are good insulators because there are no free electrons or ions (unless dissolved or melted).

They have high melting points and high boiling points. High temperatures are required to overcome the attraction between the positive and negative ions in ionic compounds. Therefore, a lot of energy is required to melt ionic compounds or cause them to boil.

A substance with metallic bonds can conduct electricity because electrons can move freely between metal atoms. Ionic compounds consist of strongly bonded ions and therefore have high melting points. ... This makes it possible for many different compounds to form.

Ionic compounds are made up of molecules as well. Ionic compounds have all the characteristics of a compound. The bond that holds the atoms together in it is ionic bond; electrostatic force of attract... ... Ionic compounds have 2 or more ions joined together by means of ionic bond into molecules.

Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.) ... Molecular compounds are electrically neutral.
