Essential Chemistry Keywords for GCSE

💡 Quick Tip: Remember that the atomic number tells you both the number of protons AND electrons in a neutral atom!

💡 Remember: The stronger the forces between particles, the higher the melting and boiling points!

💡 Pro Tip: Always check your units when doing calculations - mixing up grams and kilograms will mess up your answers!

💡 Memory Trick: OIL RIG - Oxidation Is Loss (of electrons), Reduction Is Gain (of electrons)!

💡 Real-world Connection: Your phone battery works through reversible chemical reactions - that's why it can be recharged!

💡 Think of it like this: Equilibrium is like a busy restaurant - customers are constantly arriving and leaving, but the total number stays roughly the same!

💡 Everyday Connection: The plastic in your water bottle, the fuel in cars, and even your DNA are all examples of organic molecules!

💡 CSI Connection: Forensic scientists use these same techniques to analyse evidence and solve crimes!

💡 Action Point: Understanding atmospheric chemistry helps you make informed decisions about environmental issues and climate change!
