D
Valence electrons
Verified step by step guidance1
Understand that electrons in an atom are arranged in different energy levels or shells around the nucleus.
Recognize that the electrons in the outermost shell are the ones involved in chemical bonding and reactions.
Recall the terminology used to describe these outermost electrons: they are called \textbf{valence electrons}.
Differentiate valence electrons from core electrons, which are the inner electrons not involved in bonding.
Note that protons and neutrons are subatomic particles found in the nucleus, not electrons.
