Understand that chemical bonding involves the interaction between atoms to form molecules or compounds.
Recall that atoms consist of a nucleus (containing protons and neutrons) and electrons arranged in shells around the nucleus.
Recognize that the electrons in the outermost shell of an atom are called valence electrons, and these are the ones that participate in bonding.
Core electrons are those in inner shells and generally do not participate in bonding because they are held tightly by the nucleus.
Therefore, the part of the atom primarily involved in chemical bonding is the valence electrons.
