What is Metallic bond?
In simple words metallic bond is the type of Chemical bond formed between the metal atoms.
Definition of Metallic Bond:
The attraction between the metals ions and the free floating electrons in the lattice structure of metal results in the formation of metallic bond.
How does metallic bonds formed?
The structure of metallic bonds are quit different from that of ionic and covalent bonds .As we know
Ionic bonds are formed from the complete transfer of electron from one atom to another atom whereas the covalent bonds are formed by the sharing of electrons.
Metallic bonds neither transfer nor share electrons ,metals having special type of 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 bond .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 acts as a glue giving the object a definite regular structure.
Examples of Metallic boning from Real Life:
Aluminum foil and copper wires are the examples of metallic bonding from daily life.

Physical Properties of Metals:
Metallic bonding give rise to the characteristics properties of metals ,which are as follow:
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 results in shiny nature of metal.
5.Metallic bonding between different metals results in the formation of an alloy.
