Explanation:
Metallic bond
It is the sharing of electrons between metal and metal .
It is not same as ionic or covalent bond .
As we know , the metals are quite big in size therefore , their electrons keep on moving in a crystal .
These mobile electrons and positively charged metals ions possess attraction due to opposite charges .
This metallic character is responsible for many characters that we observe in metals like good conductor of heat and electricity etc .
Metals behave as good conductor
The reason behind being good or bad conductor is to have free mobile electrons that can act as carrier and conduct electricity .
On the other hand , good conductor is often good conductor of heat because heating effect is the application of electric current
