Why are metallic compounds usually good conductors of electricity?
The electrons in their valiance band are loosely bound and generally form a cloud of free conduction band electrons filling the metal.
What is the effect of electrons held loosely?
__________ electrons are loosely held to a positive nucleus.
In order to conduct an electric current a substance must contain a what?
It should contain some IONS, or charged particles.
Why does copper conduct electricity better than lead?
Good question. Metals conduct because of the sea of free electrons in the crystal lattice. Metal conductivity depends on how loosely these electrons are bound to the nuclei and how many free electrons. Most other properties of Cu and Fe are comparable. One possible reason is the electron configuration. For Cu, it is (2, 8, 18, 1) for (s,p,d,f) orbitals, respectively. For Fe, (2, 8, 14, 2). Cu has one 4s-orbital electron that can roam freely, because all 3d electrons are paired and act as a shield from the nucleus. Fe's outermost shell is filled with 2 electrons and the 3d shell is not filled. The 3d electrons do not roam as free as 4s electrons. Cu also has more count of electrons than Fe.
Why are metals good conductors of electricity?
Because metals release negative ions which conduct electricity. Because of the force of attraction between valence electron and also because the free electrons can move freely through the lattice carrying a charge.
Does metal reflect?
Yes. Metals have outer electron shells with very loosely attached electrons; this enables metals both to conduct electricity and to reflect photons.
Why do metals conduct electricity well?
Because the valence (outermost) electron shell of a metal atom is less than half full, the electrons are loosely held in that orbit and are able to break away from that atom to become 'free electrons'. These free electrons are then able to perform as charge carriers, the drift of which, we call an electric current.
Explain how Metallic bonds allow electricity to flow?
Metallic bonds are able to conduct electricity only when they are dissolved in a liquid substance or when in molten, this is because these conditions cause the metallic bond to break down and allow the electrons used in the bond to be delocalised and disposited around the molten or liquid. This sea of free electrons is then able to pass through a current and conduct electricity.
Why are metallic compounds usually good conductors of electricity?
The electrons in their valiance band are loosely bound and generally form a cloud of free conduction band electrons filling the metal.
What are materials called in which the electrons are loosely bound?
Materials in which the electrons are loosely bound are called conductors.
What is the effect of electrons held loosely?
__________ electrons are loosely held to a positive nucleus.
Why are metals good at conducting electricity?
Metal particles are held together by strong metallic bonds, which is why they have high melting and boiling points. The free electrons in metals can move through the metal, allowing metals to conduct electricity. Metal is a good conductor because it absorbs heat easily. Whether hot or cold.
Why do metals like copper conduct electricity?
The outer electrons in a metal atom are loosely held, as a result they are easily moved from one atom to the next, transferring energy with it. When this happens though a piece of metal in one direction this energy gets transferred from one electron to the next, in a sort of domino effect
Why non metals cannot conduct electricity?
Because they are not dense enough and do not have enough free electrons to pass electricity efficiently. Although electricity can pass through non-metals if enough energy is present, for example lightning travels through many miles of air before it hits the ground.
Why does copper conduct heat better than steel or brass?
Yes/ brass does conduct heat, but not as much as aluminum and copper.
Explain how does the sea of electrons model of metallic bonding explain the shared characteristics of metals?
Basically, electricity is a force caused by electrons hitting each other. The electron sea model explains the conductivity of transition metals by showing that they hang onto their many electrons loosely and are practically floating in them. With so many free electrons, it's a lot easier to conduct electricity.
What causes electricity to flow?
Electrical conductors (wires) are primarily made of copper or aluminum. All metals will conduct current. Conductors are elements that have 1 or 2 electrons in the outer (valance) shell of their atoms. These electrons are loosely held or are already floating around in the crystalline lattice of the material. When a voltage is applied to a conductor, these electrons move from negative to positive, since electrons have a negative charge (like charges repel, unlike charges attract).
