Which 2 properties of copper depend on the delocalized electrons to flow through the metal?

Electrical Conductivity is pretty obvious. Copper is an excellent conductor due to delocalized electrons.
The second property is a little more tricky... but we know that copper (and many metals are very malleable). Salts, and various crystals are not malleable. So... a quick internet search shows up with:
Metallic Bonding
According to Wikipedia:
http://en.wikipedia.org/wiki/Metallic_bond
Electron Delocalization is one of the primary factors for Metallic Bonding.
The properties of metallic bonded materials include:
- strength
- malleability
- ductility
- thermal conductivity
- electrical conductivity
- opacity
- luster

What gives metals their distinctive properties?
the molecule structure of the metal example: copper conducts electricity so well because their loosly bound electrons, thay let the current flow through
Why electrons path is helical?
In a copper wire each copper atom has two loosely coupled outer thermal atoms (this is why copper has a plus 2 valence)When an electrical current is passed through the copper wire, the two thermal atoms are pushed onto the next copper atom. Temperature of a copper atom depends on how fast the electrons orbit in the respective copper atoms.Since thermal electrons make up the electric current which flows through the copper wire, the electrons will continue to orbit the copper atoms as they move across, thus travelling along a helical path
How does the structure of a metal allows it to carry an electrical current?
Yes they can. In general, you would use copper wire for conducting electricity, since it gives quite good characteristics and is readily available. Other materials work, but not as well.
What is the net charge of a copper atom if it gains two electrons?
Copper loss electrons.
Copper metal conducts electricity through electrons whereas it solved solution conducts electricity through ions do you agree?
no,if it is dissolved in solutions it conducts electricity through electron the electricity means flow of electrons.
Why Sodium is softer than copper but both are good conductors?
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
Is copper considered as an ionic compound?
Copper is not considered an ionic compound. The only ions it it are cations, which are held together by the metallic bonds of delocalized electrons. Furthermore, copper is an element, not a compound at all.
Why does samples of platinum and copper can have the same extensive properties but not the same intensive properties?
Samples of platinum and copper can have the same extensive properties but not the same intensive properties for a couple of reasons. These are both metals but have differing numbers of electrons.
What is a substance that allows electricity to pass through it easily?
A substance that allows electrons to pass through easily is a transition metal. Transition metals organize forming a sea of delocalized electrons and metal cations, allowing electrons to pass through easily.
How we are getting such large amounts of electrons that are flowing continously from a copper in a dynamo and Is there any limit or any chance for electrons from the copper will deplete one day?
The electrons flowing from the copper in a dynamo return back to the copper through the return circuit. That is the electrons leave through the negative terminal (opposite to that of current) and re-enter through the positive terminal.
Is copper conduct electricity a chemical change or a physical change?
It's neither since the copper isn't changing at all. Electrons are just flowing through the copper atoms.
Why pure copper is ductile and malleable?
Copper is a metal and metals got free electrons which are not allococated to a specific nucleus. These free electrons slide over each other and causes the ductile and malleable properties of metals.

How many electrons in copper?
Copper is a metal element. There are 29 electrons in a single atom.

Yes they can. In general, you would use copper wire for conducting electricity, since it gives quite good characteristics and is readily available. Other materials work, but not as well.
What is a conductor in the scientific way?
A conductor is something that can carry the electrons (electricity) through it. An example is copper. That is why copper is used for wiring. it is a good conductor.
