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.
Because the electrons of different metals have different energy levels.After the electrons go to the excited state, they want to go back to the ground state. There will be photons (lights) emitted when electrons go back to the ground state. Different photons (lights) have different wavelengths so we can see different colors

Not all the photons emitted will be of a frequency in the visible light spectrum. Thus there is energy emitted that we may not see.

When the metal salts burn, the electrons get 'excited' and jump from the ground level (they are in this state 99% of the time) to a different energy level, then back to ground level. During these jumps, the electron releases packets of energy called photons. These photons have have different wavelengths and frequencies (which have a specific place in the visible light spectrum). Thus these photons have different colors which can be seen when the metal salt burns

Different color of flame are made out of different elements and metal, the color can also be determined by the amount of photon is interacting with the electrons, and when the interaction happened, the energy level of the atom will increase. The more energy that the electrons is holding, the larger the wavelength, which is what changes the colors of the flame.

The reason as to why the different metal salts burn in different colours is that when the electron moves to an excited state, and then drops back down to the ground state, it emits a certain frequency and wavelength of a photon.

When the fire first starts the colour of the flame is blue which is the methanol burning, as the salt dissolves the colour of the flames settle more clearly with each colour flame having a direct relation to the metal that is burning, and the relation that is that the metal that is burning is gaining energy and when the energy is released which is also known as photons which is what gives the colours of the flames

All metal salts will emit photons of a certain wavelength and frequency, and the visible part of that photon will be seen by us as colors of the light. However, when it comes to different types of metal salts, the color of light changes correspondingly.

Very helpful in understanding this topic but would be good to include that they change based on reactivity
