define metallic bond?

Answer 1

Metallic bond is the bonding between metals.
Positive ions of metals are arranged in a regular, 3-D lattice and these ions occupy fixed position in the lattice. The electrons are delocalised and therefore they can move freely in the lattice. Because electrons are negatively charged. There will be attraction between the positively charged ions and negatively charged delocalised electrons and this attraction force hold them together, and this is called metallic bonding!
* ions are atoms that lost or gain one or more electrons.Metals usually form "cations" because they always lost one or more electrins to form positively charged ions *

Answer 2

1: Metallic bonding is an attraction between metal ions. Well, it is yes and no. Metallic ions are all positive, and positive charges repel, not attract. However, in a metal, the valence electrons are free to move around from place to place leaving the original atoms as positive ions. The free floating electrons that carry the negative charge serve as the "cement" that binds the positive ions together. 2: All metals contain delocalized electrons. This is correct, as I explained in #1. 3: Metallic bonds enable metals to be bent. This is also true due to the above-described metallic bonds. The "delocalized electrons" allow bending and re-shaping of metal without breaking it. 4: All metals conduct electricity and heat This is true. The fast moving free electrons carry the electrical charge easily from place to place if an electrical potential is applied to a metal. They can also carry the heat energy. 5: All metals are solid at room temperature. Most metals are solid at room temperature, but at least one is liquid at room temperature. The best example is mercury that can be used inside a thermometer. 6: An alloy always contains two metals. An alloy is a mixture of at least two metals, although it could easily contain more metals. An alloy is not a compound, since unlike the compounds, metals can be combined in any proportion.

RE:
define metallic bond?

Answer 4

Metallic bonding is bonding within metals. It involves the delocalised sharing of free electrons between a lattice of metal atoms.

Answer 5

The chemical bond characteristic of metals, in which mobile valence electrons are shared among atoms in a usually stable crystalline structure. A bond bewteen two or more metallic elements; based on the property of metals to give up electrons.

Answer 6

i don't really know what it is (because i didn't learn chemistry in English) but I suppose that it refers at the process of metal crystallization. It's quite simple: the metal molecules are bound together and they share electrons, kind of like the covalent bond at the non-metals. The electrons that are expelled form the molecule stay in the crystal and are called Free electric charged particles. They are the reason why metals can conduct electric current.
