Metallic Bonding
Metallic bonding is the type of bonding in which positively charged metal ions are surrounded by a "sea" of delocalized electrons, which are free to move throughout the solid. This type of bonding produces a solid that reflects light in the visible region, as the delocalized electrons can absorb and re-emit photons in this range of the electromagnetic spectrum.
Electrical Conductivity
The delocalized electrons in metallic bonding also give rise to the high electrical conductivity of metals. These electrons can move freely through the solid, carrying electric charge with them. However, as the temperature of the solid increases, the atoms vibrate more and more, disrupting the movement of the delocalized electrons. This leads to a decrease in electrical conductivity with temperature.
Melting Point
The strength of metallic bonding also leads to a high melting point. In a metal, the positively charged ions are held together by the attraction to the negatively charged delocalized electrons. This attraction requires a large amount of energy to break, resulting in a high melting point.
Conclusion
In summary, metallic bonding produces a solid that reflects light in the visible region, has a high electrical conductivity that decreases with temperature, and a high melting point. This makes metals useful in a variety of applications, from electrical wiring to construction materials.

Metallic bonding is formed due to attraction of valence (free) electrons with the positive ion cores.Their conductivity decreases with rise of temperature.When visible light falls on a metallic crystal, the electrons of atom absorb visible light, so they are opaque to visible light.
•However, some orbital state.They then return to their normal state, remitting light of same frequency.
