⚠️ 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. The idea of electrons in fixed circular paths is a simplification used at GCSE — the real picture is more complex and is studied at A-level. 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.
