Core electrons
D
Bonding electrons
Verified step by step guidance1
Understand that electrons in an atom are arranged in energy levels or shells around the nucleus.
Recognize that the outermost energy level of an atom contains electrons that are involved in chemical bonding and reactions.
Learn that the electrons in this outermost shell are called \textbf{valence electrons}.
Differentiate valence electrons from core electrons, which are the inner electrons not involved in bonding, and free electrons, which are not bound to any atom.
Conclude that the correct term for electrons in the outermost energy level is \textbf{valence electrons}.
