What is the highest main energy level of Cl? How many inner shell electrons does Cl have?

The highest energy level in which you would find electrons in a ground state chlorine atom is the third energy level.

Explanation:

The highest energy level in which you would find electrons in a ground state chlorine atom is the third energy level.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
