What is metallic bonding, how does it work, and is it strong or weak and why?

I'll try my best.

Metals love to share electrons. In metals, the electrons are feebly bound to the nucleus, so when metals come into contact with each other they lose their outer electrons. Now all the atoms have a positive charge and they are attracted to the electrons that freely move throughout the metal. This gives metals properties such as high electrical conductivity, malleability and ductility. Metallic bonds are fairly strong as most metals have high melting points, but strength depends on the metal's properties.
