GENERAL KNOWLEDGE

Detailed explanation-1: -Metals are good conductors of electricity because they have free electrons. These free electrons act as charge carriers in the metallic structure, allowing electric current to flow through them.

Detailed explanation-2: -Metals are excellent conductors of electricity and heat because their atoms form a matrix through which outside electrons can easily move. Instead of orbiting their individual atoms, they generate a sea of electrons around the positive nuclei of the interacting metal ions.

Detailed explanation-3: -Since the electrons are not strongly bonded to the positive nucleus, they are free to move. Hence, the electrons in a conductor can move without much restriction when an electric field is created in the conductor.

Detailed explanation-4: -Metals atoms have loose electrons in the outer shells, which form a ‘sea’ of delocalised or free negative charge around the close-packed positive ions. These loose electrons are called free electrons. They can move freely throughout the metallic structure.

Detailed explanation-5: -Metals are substances that have the tendency to donate electrons. They are electropositive in nature. In metals the electrons in the outermost shells are loosely bound to the nucleus. Even at room temperature, there are a large number of free electrons which are moving inside the metal in a random manner.
