One property of most nonmetals is that they are what?
High ionization energy and poor electrical conductivity
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.
why does metal's electrical conductivity gets better when the temperature is cooler?
First, let me explain why metals generally conduct heat better than other solids do. In metals, some of the electrons (often one per atom) are not stuck to individual atoms but flow freely among the atoms. Of course, that's why metals are such good conductors of electricity.
Is alkali metals a group 1 elements?
No that is group 2. Group 1 is called Alkali metals.
Do group one metals have a high melting point?
No. Group 1 metals (commonly called the alkali metals) have low melting points.

How can you put conduct in a sentence?
Electrical conductivity is one important factor among the differences between various metals.
List three properties of metals that are a result of metallic bonds?
Mallabillity, conductivity of electrons, conductivity of heat, shining 'silvery' glance
Why minerals are metal and non-metal?
Metals considered minerals are composed of one element. Those elements considered metallic have some shared properties in electrical conductivity and luster.
Does copper have a electrical conductivity?
Yes, indeed: one of the highest electrical conductivities of any known substance.
The electrical conductivity of metals which is expressed in ohm-1 m-1 is of the order of?
In the range of 1 x 10^7 1/ohm-m . That's one times ten to the seventh power.
One molecular solid which exhibit electrical conductivity?
The graphite form of carbon.
What is the physical significance of Nernst-Einstein equation?
The equation relates the electrical conductivity to the diffusivity of its anion and cation constituents. While electrical conductivity is relatively simple to measure, diffusivity is a bit more complicated. Measuring the electrical conductivity of a solution or melt one can study materials properties and interaction.
Why conductivity of diamond is highest being a nonmetal?
It would help if you specify whether you are talking about thermal conductivity, or electrical conductivity. Diamond certainly doesn't has the highest electrical conductivity. Its thermal conductivity is one of the highest known, and - if a synthetic diamond is made from pure (99.9%) C-12, it is indeed the highest. The Wikipedia article attributes this to a strong covalent bonding.
Electrical conductivity of copper?
Copper in one of the most electrically conductive of substances. Few materials have more conductivity. These include platinum, gold, and silver.
Electrical conductivity when dissolved in water?
The electrical conductivity of different materials is affected differently when dissolved in water. For example, anhydrous Sodium Chloride changes from a non-conductor to a one when dissolved.
