Answer
The correct answer is B: Protons and neutrons.
Explanation
The correct answer is B: Protons and neutrons. This supports the learning objective "Explain why an atom has no overall electrical charge when it contains equal numbers of protons and electrons." in The structure of an atom because it uses the correct atomic and nuclear radiation relationship for Atoms and isotopes. The other options are less suitable because they do not match the required The structure of an atom idea: Electrons and protons; Neutrons and electrons; Only protons.
Common mistake
Understanding Electrical Charge in Atoms
Students often think that an atom has a charge because it contains protons and electrons.
Emphasize that an atom is neutral overall when it has equal numbers of protons and electrons, as their charges cancel each other out.
