Best Answer

When metal corrodes, it forms an ionic bond with some corrosive nonmetal such as oxygen or sulfur, and once it forms such a bond, its valence electrons become tremendously less mobile, since they are caught by the nonmetal. The high electrical conductivity of metal depends upon the mobility of the valance electrons.

What causes low conductivity.... metal plus metal or non-metal plus non-metal or metal plus non-metal?

well, not metal+metal, but for the other 2 you'd have to specify, because water+metal=good conductivity & just water or another liquid = good conductivity. now stone, it is a horrible conductor.


What metals are most affected and least affected by metal corrosion What causes metal corrosion Hows is metal corrosion caused by water and how is it related to it?

Corrosion is a chemical reaction; corrosion of iron is the reaction with water in the presence of oxygen. Metals as Pt, Au, Ta, Rh, Ru, etc are less sensible to corrosion.


Why does the conductivity of a metal increase when a metal is cooled?

conduction is basically the flow of electrons from one end to the other in a conductor. lets take the example of a metal rod. the metal rod can conduct electricity as the electrons are able to flow and the resistance offered by the cations is relatively low. however, when the metal rod is heated, the cations start vibrating as energy is supplied to them. vibrating cations cause greater hindrance to the movement of electrons and thus, the conductivity decreases.
