Which statement is true regarding copper's ability to conduct electricity?

Copper is a good conductor of electricity because its atoms have a loosely held electron in their outer shell that is able to move freely to other atoms.

Copper is a poor conductor of electricity because its atoms are held in positions that cannot move.

Copper is a good conductor of electricity because its atoms have electrons that are tightly bound to their shells and will resist movement.

Copper is a poor conductor of electricity because it has a free electron in its outer shell that will flow to other copper atoms.

Copper is a good conductor of electricity because its atoms have a loosely held electron in their outer shell that is able to move freely to other atoms.

Answer:

(i) Copper is a good conductor of electricity because its atoms have a loosely held electron in their outer shell that is able to move freely to other atoms.

Explanation:

Copper atoms has loosely held electrons in their outer shell. These electrons are not permanently associated with the copper atoms, instead They make a cloud around the outside of these atoms and are able to move freely and quickly through the solid.

Option (ii) cannot be selected because copper is a good conductor. For the conductivity, free movement of electrons is a condition which is unsatisfied in the (iii). In (iv), it is given that copper has 1 electron in the outermost shell which can flow to the other copper atoms which is not true because in copper many atoms can flow to other atoms.
