⚠️ Common Misconceptions
Misconception 1: "Electrons orbit the nucleus like planets orbit the Sun"
The Bohr model is a useful simplification for GCSE, but electrons do not follow simple circular orbits. They exist in probability clouds (orbitals) and can only be described by quantum mechanics. At GCSE, treat shells as energy levels, not physical tracks. The "orbit" language is an approximation.
Misconception 2: "Neutrons have a negative charge"
Neutrons have NO charge — they are neutral (hence the name). Only protons (+1) and electrons (-1) carry charge. The confusion arises because "neutral" can sound like it means "negative." Remember: neutrons are in the nucleus with protons, and if they were negative, the nucleus would repel electrons rather than attract them.
Misconception 3: "Isotopes of an element have different chemical properties"
Isotopes have identical chemical properties because chemical behaviour is determined entirely by the number of electrons, which equals the number of protons — unchanged between isotopes. Different neutron counts only affect mass (and nuclear stability), not chemical reactions.
