검증된 단계별 안내1
Understand that chemical bonding occurs due to interactions between atoms aiming to achieve stable electron configurations.
Recall that the nucleus (containing protons and neutrons) is located at the center of the atom and is not directly involved in bonding.
Recognize that electrons occupy energy levels or shells around the nucleus, and those in the outermost shell are called valence electrons.
Know that valence electrons are the ones that participate in forming chemical bonds by either being shared, transferred, or pooled between atoms.
Conclude that the part primarily responsible for chemical bonding is the valence electrons, not the nucleus or its components.
