Verified step by step guidance1
Understand that an atom is composed of different subatomic particles organized into distinct regions.
Recognize that the nucleus is the central part of the atom, containing protons and neutrons tightly bound together.
Know that surrounding the nucleus is the electron cloud, which is the region where electrons are likely to be found.
Identify that the two main parts of an atom are therefore the nucleus and the electron cloud, representing the core and the surrounding area respectively.
Distinguish this from other options that list particles or entities rather than the structural parts of the atom.
