What is Metallic bond?

In simple words, a metallic bond is the type of Chemical bond formed between metal atoms.

Definition of Metallic Bond:

The attraction between the metal ions and the free-floating electrons in the lattice structure of metal results in the formation of a metallic bond.

How do metallic bonds form?

The structure of metallic bonds is quit different from that of ionic and covalent bonds. As we know

Ionic bonds are formed from the complete transfer of electrons from one atom to another atom whereas covalent bonds are created by the sharing of electrons.

Metallic bonds neither transfer nor share electrons, metals having a special bonding where the valence electrons delocalize. Its means that instead of orbiting their respective metal atom they form a sea of electrons floating around the positively charged nuclei.

Delocalization of electrons in the metals is due to their big size resulting in the decrease of nucleus hold on valence shell electrons so the electrons can freely move around the atomic nuclei.

What type of bond is the metallic bond?

Is metallic bond ionic or covalent!!!

we can easily differentiate between ionic covalent and metallic bonds. As the ionic bond is formed between metal and nonmetal. For example, Sodium Chloride NaCl whereas the covalent bond is formed between non-metals. For example H2, Cl2, F2 etc.

Remember that the metallic bond is formed between the metal atoms. A metallic bond is the sharing of many detached freely floating electrons between many positively charged ions, where the electrons act as a glue giving the object a definite regular structure.

Examples of Metallic boning from Real Life:

Aluminium foil and copper wires are examples of metallic bonding from daily life.

Physical Properties of Metals:

Metallic bonding gives rise to the characteristics properties of metals, which are as follows:

1. Metals are good conductors of heat and electricity.

Do you Know!!

Why metals are good conductor of electricity?

Metals are good conductors because the free electrons in the electron sea can easily flow and thus carry electricity.

2. Metals are malleable (can be molded into different shapes) and ductile (can be stretched into wires).

3. Melting point and the boiling point of metals are high.

4. Metals are lustrous (shiny)because the light cannot penetrate their surface and reflect off resulting in the shiny nature of metal.

5. Metallic bonding between different metals results in the formation of an alloy.
