Common mistake
Relative Charge Confusion
Students often confuse the relative charge of protons, neutrons, and electrons, stating that neutrons have a negative charge.
Remember that protons have a relative charge of +1, neutrons have a relative charge of 0, and electrons have a relative charge of -1. To clarify: Protons: +1, Neutrons: 0, Electrons: -1.
