Question
Explain why an atom is electrically neutral when it contains equal numbers of protons and electrons.
Answer
An atom is electrically neutral because the positive charge of the protons cancels out the negative charge of the electrons, resulting in no overall charge.
Explanation
This question assesses the student's understanding of atomic structure and charge balance. It requires them to apply their knowledge of protons and electrons to explain the neutrality of atoms.
Common mistake
Charge Confusion
Students often confuse the relative charges of protons, neutrons, and electrons, thinking that neutrons have a negative charge.
Remember that protons have a positive charge, electrons have a negative charge, and neutrons have no charge.
