It is metallic bond, because you know yea metallic is metal and meteal collect electric, so it mean it free to move so the electricity pass through the meatal and when u tough it you may die exacly.

Why electron freely in a metal?
The term conductor is generally applied to a substance or material that has a lot of free electrons in it. The name conductor is applied because the free electrons are already there. A material does not have free electrons because it is a conductor, but is a conductor because it has a lot of free electrons. That said, let's look at what's going on. These free electrons have energies that permit them to "wander" through the conductor; they're not "locked into" the structure of the material. And when a voltage (potential difference) is applied, current flows through the conductor because the free electrons are moving. They're made to move by the applied voltage. If we take the case of a wire in a circuit, the wire is a conductor. This wire, say a copper one, has many free electrons in it, and when we apply a voltage, electrons move. The voltage forces electrons into one end of the wire, and the free electrons "shift over" and electrons emerge from the other end of the wire. This movement of free electrons in response to an applied voltage through an conductor is the essence of current flow in that conductor.
What type of bond is formed when many atomic nuclei and core electrons of an element form a core and the valence electrons from all the atoms are free to move throughout the structure?
metallic bond
Why are non-metals not shiny?
Metals are shiny because their outer electrons not attached to any particular atom but are free to wander throughout the material with little resistance. This is also what makes metals conductive. So when light shines on metal it sets these free electrons into vibration so instead of energy springing from atom to atom it's reemitted as visible light. However, nonmetals may not have this property and therefore aren't shiny.
What is a conductor and a insulater?
A conductor is any material in which electrons are free to flow, whereas an insulator is any material in which the electrons are tightly bound to the molecules with which they are associated.
What substance that allows the flow of free electrons?
Material that permits the free flow of electrons
What is material that will not release electrons nor allow free electrons to pass?
Insulator
A material with many free electrons is referred to as a good what?
semiconductor
A material used for electrical wiring must have what?
free electrons
Why is wood a poor cunductor?
conductivity closely relates to the number of free electrons , and in the wood material the electrons are not present in free state.
How many valence electrons does insulator have?
It is not the number of valence electrons that an insulator has that is important. It is the way the valence electrons are "arranged" in the structure of the material that matters. If not all the valence electrons of a substance are "involved" in the structure of the material, then these electrons are said to be free electrons. They move about in the substance, and are free to contribute to electron flow. The metals are examples. In contrast with this, if all the electrons are bound up in a material, they are not free to support current flow, and the material is said to be an insulator. Said another way, if the valence electrons in a material are in a Fermi energy level that overlaps the conduction band for that material, the material is a conductor. In an insulator, the valence electrons are all in Fermi energy levels that are below the conduction band for that material, and it is an insulator. Applying a voltage to an insulator will not "lift" the valence electrons up into the conduction band to allow them to support current flow.
What types of materials conduct heat?
Any material that has free electrons.
A material used for electrical wiring must have?
free electrons
Is a material a good insulator if outer electrons of atoms in the material are free to roam around?
Freely moving electrons make materials more conductive, and less insulating.
How does an electrical insulator work?
Any material that does not allow the free flow of electrons.
