Conductivity in a metal results from the metal atoms having?
highly mobile electrons in the valence shell
What specific property of metals accounts for their unusual conductivity?
Outermost orbital shell of a metal has very few electrons with corresponding values of energy. This specific property accounts for the unusual electrical conductivity of metals. Highest conductivity occurs in metals with only one valence electron.
What are some physical properties of valence electrons?
The valence electrons influence many properties and characteristics of a material. The properties of a material which are influenced by the valence electrons are chemical properties, electrical conductivity, some mechanical properties, the nature of inter atomic bonding, atom size, and optical characteristics.
What is valency of aluminium in aluminium oxide?
AL2O3: Aluminum has three valence electrons to give, the oxygen atoms can accept 2 valence electrons. With the compound being made of 3 oxygen atoms (which have 6 valence atoms individually) they accept 2 of the aluminums valence electrons. In electrical practice, this compound is an insulator. One atom or compound having 6-8 valence electrons is electrical insulator.
What is the relationship between the number of valence electrons and the conductivity of the given elements?
Less valence electrons (1 to 3) in the outermost shell of an atom usually means a good conductor. (silver, cooper, gold). 5 t0 8 valence electrons are found in glass, rubber, ceramic, plastic, non-conductors.
Why metal are good electrical conductivity?
Delocalized valence electrons

The valence electrons found in metallic bonds give metals which characteristics?
Free- Roaming electrons, and conductivity

Why are the valence electrons found in metallic bonds different from other bonds because of what?
their valence electrons are free-roaming they allow for the conductivity of electricity APEX :) <3 JAmie
Why does corrosion of metal decrease conductivity?
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 is the relationship between the number of valence electrons and conductivity of a given element?
I suppose that a relation doesn't exist.

How do the valence electrons in metals determine the properties of solid metals?
The valence electrons in a metal are held in delocalised orbitals which cover the whole lattice. This means that they are free to move through the whole structure. This freedom gives metals their special properties such as good electrical and thermal conductivity (because the electrons move easily) and malleability and ductility (because they bond the atoms together in any configuration).
What are metal atoms held together by?
The electrons in the valence band of metals escape and form an "electron gas" filling the bulk of the metal. The positively charged nuclei of the metal are attracted to this diffuse negatively charged cloud of delocalized conduction band electrons. This gives metals their well known properties of ductility, malleability, electrical conductivity, thermal conductivity, etc.
