Science - Exploring Chemical CompoundsPosted on: 19/05/2022
We are all used to flame being yellow-orange. But can we turn a flame to a different colour? Last Monday Y10 chemists explored different chemical compounds at an atomic level. They used a simple flame test to observe the colour of light produced when various metal compounds are burned.
Many ions of metals and non-metals turn flame different colours. This is because when heated, atoms move to an excited (or unstable) state. When they return to their original (stable) state, the excess of accumulated energy is released in the form of light of a certain wavelength, which is characterised by the colour we observe. This amazing property is used to make coloured fireworks.
Students will be looking at this in more detail in GCSE and A-level Chemistry.
A huge thank you to the following Y12 scientists for their help: Mania, Anuyah, Roberto, Elona, Moska, Fardous and Yasmin.
Congratulations to Sienna (7N) for making it into the top 5 in the Bayer annual lab coat design competition. Best of luck for the final round of judging!
