Glass, porcelain, plastic and rubber are examples of non-conductive materials. These materials are also known as insulators. They are used to stop the flow of electricity.Know More
Insulators either prevent or block the flow of electrons. The atoms inside insulators do not have extra electrons that can move freely through a material. However, there is no such thing as a perfect insulator since an insulator can become electrically conductive.
The opposite of insulators are conductors. Examples of conductors include copper, aluminum, platinum, gold, silver, ionized water and trees. Conductive materials are compounds that are comprised of atoms with free electrons. These electrons are able to move freely through the conductive material and allow electricity to flow.Learn More
There are no non-conductive metals; all metals conduct electricity, though some do this more effectively than others. Thanks to the molecular structure of metals, they are all relatively effective conductors, though silver is the most conductive metal known to man.Full Answer >
Acetone is considered a polar molecule because it contains an imbalance of electrons. Acetone shares some properties with nonpolar molecules, such as being water soluble.Full Answer >
Sodium is considered a metal, as it is part of the alkali metals group. The other members of this group include lithium, cesium, rubidium, potassium and francium.Full Answer >
A non-polar molecule is a molecule with polar bonds but having a symmetrical molecular structure, or a molecule containing atoms of equal or almost equal electronegativities. The electrons in a non-polar molecule are evenly distributed with respect to the origin.Full Answer >
