Verified step by step guidance1
Understand that atoms are composed of three main subatomic particles: protons, neutrons, and electrons.
Recall that protons and neutrons are located in the nucleus of an atom, while electrons orbit the nucleus in electron clouds or shells.
Recognize that chemical bonding involves the interaction between atoms to achieve a more stable electron configuration.
Identify that electrons, particularly those in the outermost shell (valence electrons), are the subatomic particles that participate in chemical bonding.
Conclude that electrons are responsible for forming chemical bonds, such as covalent, ionic, and metallic bonds, by being shared, transferred, or pooled between atoms.
