Why Do Some Substances Conduct Electricity and Some Not

I believe you mean inorganic substances commonly conduct electricity while organic compounds dont. They consist of oppositely charged ions.

Many substances do not dissolve in water and that is because they are non-polar and do not interact well with water molecules.

. These ions are free to move to conduct electricity. Its a natural that most would like to spend less money on. Sometimes when two different solutions are mixed the substances they contain react with each other and form ions.

That means that a material with a large band gap at the Fermi surface is an insulator it cant conduct electricity easily. A materials or an object that conducts heatelectricitylight or sound is called conductorsMetal wires are good conductors of electricity and offer less resistance to the flow of currentWhy metals conduct electricityMetals like silver and copper have excess of free electrons which are not held strongly with any particular atom of metalsThese free electrons move randomly in all. Oil contains molecules that are non-polar thus they do not dissolve in water.

Interestingly aqueous solutions with ions conduct electricity to some degree. Getting power is powered by a non-electronic source a windmill. Most molecular substances do not conduct electricity since the ions dont dissociate very well with molecular substances.

For example NaCl consists of Na and Cl ions arranged in a crystal lattice. This is what happens when ammonia and vinegar are mixed. The ions in the crystal cannot move.

Thus ionic compounds conduct electricity in molten state or solution but in solid state they do not conduct electricity. While in a solid state the ion bonds are firmly held together and the charged particles can not move freely. This is why ions do not conduct.

In contrast the structure of organic substances which is mostly C-H bonds does not allow charge to pass freely. Compounds of metals do not conduct electricity as a solid but metals are good conductors of electricity. When sugar is dissolved in water the solution does not conduct electricity because there are no ions in the solution.

Sugar is such a substance. I VR Some substances have H ions to conduct electricity and others do not. Evidence As the resistance of a material increases its conductivity goes down so the amount of current that it conducts must also decrease according to Ohms law.

A common example is oil and water. Electric charge travels through charge carriers These can be electrons which carry negative charge. Why do some substances conduct electricity and some not.

For example if you took table salt NaCl and dissolved it in water the salt would dissociate into Na and Cl. In molten state or dissolved state ionic compounds conduct electricity because they contain charged particles called cations and anions. An electric current consists of the movement of charged particles.

An ammonia solution contains only a few ions and it conducts electricity only poorly. However most ionic substances do conduct electricity very well due to. Some are mode of uncharged particles called molecules.

For a substance to conduct electricity it needs to contain some sort of charge carrier - this could be an electron or an ion - that is free to move within the substance. There are also scenarios where unpaired electrons can also be free to conduct charge. When sugar is dissolved in water the solution does not conduct electricity because there are no ions in the solution.

Ionic compounds conduct electricity only when molten or in solution as the lattice structure breaks up allowing the ions to be free to move. Are mode of uncharged particles called molecules. This is because they do not have charged particles which are free to move.

The reason why substances conduct electricity while others do not. Click to see full answer. In the left-hand cartoon there is a big gap between the filled and empty bands so its very difficult for an electron to gain enough energy to make the jump from the filled band to the empty band.

Some are mode of uncharged particles called molecules. The main reason is a windmill is used is to generate power. Some substances that are made of molecules form solutions that do conduct electricity.

Whereas it contains electricity in molten or aqueous state due to the presence of free ions. Na basically steals an electron from Cl. When an ionic substance is molten or dissolved the ions that make it up are free to move within the substance and carry.

A windmill is kind of like a solar panel. Rosariomividaa3 and 3 more users found this answer helpful. This is why laundry ammonia which is a solution of ammonia in water conducts electricity but not very well.

Why Does Water Conduct Electricity. In order for compounds to conduct electricity there must be charged particles present - such as the case with ionic compounds which are composed of positively or negatively charged ions. Ion Conduction Unlike metals which conduct electricity by free electrons water conducts electricity by moving charged ions.

Generally speaking they do not - though there are exceptions. Sugar is such a substance. In general covalent network substances do not conduct electricity.

An ion is an atom with a net positive or negative charge. Conductors conduct electricity because most of them are made ofmetals and metals are good conductors of electricity whileinsulators are made of rubber and rubber does not conductelectricity. When in a liquid or aqueous state Ionic compounds contain charged ions called anions and cations and these particles make sure that the ions are free to move from place to place and eventually conduct electricity.

When a solute dissociates in water to form ions it is called an electrolyte due to the solution being a good electrical conductor. Some substances that are made of molecules form solutions that do conduct electricity. Substances can conduct electricity if there is a way for charge to flow through that substance.

Therefore pure water will not conduct electricity. Why do some substances conduct electricity and some not. Ionic compounds contains high electrostatic force thus it exists in solid state and does not loose its ions hence does not conduct electricity.

Compounds of metals are salts. Pure water having a very low concentration of ions cannot conduct electricity.
