Verified step by step guidance1
Understand that electrons in an atom are divided into core electrons and valence electrons. Core electrons are those in the inner shells, closer to the nucleus, and are not typically involved in bonding.
Recognize that valence electrons are the electrons in the outermost shell of an atom. These electrons are the ones that participate in chemical bonding because they can be shared, gained, or lost to form bonds.
Note that excited electrons are electrons that have absorbed energy and moved to a higher energy level temporarily, but this is not a classification of electrons involved in bonding.
Free electrons refer to electrons that are not bound to any atom or molecule, often found in metals or plasma, and are not specifically the electrons forming bonds.
Therefore, the electrons involved in the formation of a chemical bond are called valence electrons, as they determine the chemical properties and bonding behavior of an element.
