Imagine a roaring bonfire on a cold winter night. The warmth radiating from the burning wood draws people closer, hands outstretched to feel its comforting heat. Now picture a cool pack used on a sprained ankle, instantly chilling the moment it’s activated. Both these everyday occurrences are examples of the same fundamental concept in chemistry: the transfer of energy during a chemical reaction. The way energy moves in a reaction determines whether it’s endothermic or exothermic....

Without a doubt, magnets are quite fascinating. From fridge doors to high-tech MRI machines, they’re everywhere. But despite how often we encounter them, many people still believe one common myth: magnets attract every type of metal. It’s easy to see where this comes from. After all, you’ve probably seen magnets stick to fridges, tools, or even bits of scrap metal. So surely they must attract all metals, right? Not quite. This misunderstanding is actually a great example of how science can...

The periodic table is one of the most fundamental tools a student uses when taking secondary chemistry tuition , serving as a roadmap to understanding the structure of matter and how different elements interact. At first glance, it may seem like just a random and colourful patchwork of symbols and numbers, but in reality, it is a highly organised arrangement of elements that reveals a surprising amount of information about their behaviours and properties. The way the table is ordered gives...
