nucleus, electrons, and quarks protons, neutron, and electrons ionic bonds, covalent bonds, and ions nucleus, electron cloud, and energy levels
I gave my students this multiple choice question: Which list describes the particles that make up an atom?

Only one answer is correct among these 4 choices:
- nucleus, electrons, and quarks
- protons, neutron, and electrons
- ionic bonds, covalent bonds, and ions
- nucleus, electron cloud, and energy levels

Could you tell me which one is correct?

protons, neutron, and electrons
