Question

Quizplus · Accepted Answer

A free electron is an electron that has been released from the valence shell of an atom, either through the process of ionization or by being excited to a higher energy level. The valence shell is the outermost electron shell of an atom, which is involved in chemical bonding and interactions with other atoms. Therefore, option D is the best choice as it correctly identifies the valence shell as the one from which a free electron is released.
