Sodium is alkali metal having only 1 electron in valance shell, while copper is transition element having 10 electrons in its outer most 3d sub shell. In copper there are more chances for overlapping of the orbitals because in Copper there are more delocalized electrons which hold the positive ions more tightly. Anyhow both have delocalized electrons that's way both are good conductor of electricity

What characteristic of copper and aluminum causes them to be good conductors?
Both are metals, and metals are great conductors, thats why copper and aluminum are very good conductors causing to that they are made and are metals. Just did my homework on this from another website this is 100% correct! Cya people, Christopher :)
Sodium is preferred over potassium in industrial applications because why?
$$$$$$ Sodium is cheaper!!!!$$$$$$ They both work great for the same purposes and are very often interchangeable. (But potassium hydroxide makes much softer and, to me, more pleasant feeling soap than sodium hydroxide)
Does an Australian five cent coin conduct electricity?
The Australian five-cent coin is composed of 75% copper and 25% nickel. Both of these metals are comparitively good electrical conductors. Copper, in particular, is the second best, after silver.
Are gold copper and silver insulators or conductors?
They are metals, and like all metals they are excellent conductors of both heat and eletricity. While both conduct but not the same see periodic table plus silver oxidizes and eventual makes a bad conductor at the joints gold is not as good conductor but is is impervious of elements effects on it.
Is sodium and chlorine metals or non metals?
Sodium, copper and aluminum are all metals. Chlorine is not a metal.
Is Brass copper a insulator?
Both brass and copper are conductors.
Why Sodium is softer than copper but both are good conductors of electricity?
In sodium and copper it is the s electrons delocalised accross the lattice that contribute to the electrical conductivity. The extra bonding due to d orbitals in copper, a transition metal, contributes to its hardness and higher melting point . Both sodium and copper have metallic bonds. Sodium is an alkali metal and there are no d electrons, wheres copper is a transition metal. In the alkali metals the only force of attraction between the metal atoms is due to the delocalisation of the s electrons. In transition metals there is an extra attraction due to the d electrons. Copper has one of the lowest heats of formation of the transition metals the d electrons contribute less than in the lighter members. Hardness is a poor measure IMHO of metallic bond strength, as hardness can be related to the density of lattice dislocations.
What are some materials that are good conductors?
metals like iron and copper These are good conductors of both heat and electricity.
Why are gold and copper good conductors?
they both have free electrons hope it helps!!
What characteristic of copper and aluminum causes them to be good conductors?
Both are metals, and metals are great conductors, thats why copper and aluminum are very good conductors causing to that they are made and are metals. Just did my homework on this from another website this is 100% correct! Cya people, Christopher :)
Are metal gold and copper good heat insulators?
No. Both metals are good conductors of heat.
What do brass and bronze have in common?
they are both metals, relatively soft, shiny, and good conductors of electricity.
What characteristic of copper and aluminum causes the to be good conductors what is the effect?
They are both metals. The effect is that copper is more safer than aluminum. From Leah :)
Is a copper wire an insulator or conductor?
Conductor, it is actually one of the best conductors for both heat and electricity.
Why are copper wires and not steel wires used in electric circuits although both are copper and steel are electoral conductors?
copper is cheaper to manufacture and easier to bend then steel
What materials is a good conductor of electricity rubber silver glass plastic?
Copper and silver are good conductors as both are metals.
What do all conductors of electricity have in common?
The best conductors of electricity have that they are all metals in common.
