Flame test - Application
Discuss why the different metal salts burn in different colours by using the theory of quantisation of energy and the information in the video "Energy levels - AS Quantum". Read your classmates comments and comment yourself on the blog post "Flame test - Application". Ensure that you do not repeat what has been said already.
Question: Energy levels and emission spectrum
Look at the picture of the hydrogen line emission spectrum (figure 1) below and discuss why this emission spectra has only certain lines rather than the whole spectra with all the colours. Use the video "Energy levels - AS Quantum" and figure 2 to help you explain using scientific reasoning.
