검증된 단계별 안내1
Recall the structure of an atom, which consists of a nucleus and an electron cloud surrounding it.
Understand that the nucleus contains particles called nucleons, which are protons and neutrons.
Recognize that electrons are found outside the nucleus in the electron cloud, not inside the nucleus.
Identify that positrons are not typically found inside the nucleus; they are the antimatter counterparts of electrons.
Conclude that the two particles found together inside the nucleus are protons and neutrons.
