검증된 단계별 안내1
Recall the basic structure of an atom: it consists of a nucleus and surrounding regions called energy levels or electron shells.
Understand that protons are positively charged particles and are located inside the nucleus at the center of the atom.
Recognize that electrons are negatively charged particles and are found outside the nucleus, moving in defined energy levels or orbitals.
Note that neutrons (not mentioned here) are also located in the nucleus along with protons, but electrons are never inside the nucleus.
Therefore, the correct description is that protons are located in the nucleus, while electrons are found outside the nucleus in energy levels.
