Flame Test Lab Report
Discussion:
There were some patterns that were noticeable during this experiment. It was noticed that all of the sprays with the metal potassium in them had turned the flame a light pink for a few seconds.
The sprays that held the copper in them all turned the flame a vivid green colour, with some including green sparks also. Both of the sodium bottles turned the flame orange for a short time.
Electrons orbit the nucleus of an atom in energy levels. If atoms are heated up to the point where the electrons are orbiting the atom shells at a faster pace than usual, the energy from the electrons when they are slowing down their pace is given off in light form, and when the energy levels are back to normal again, the colour of the flame is back to the luminous blue light. Different atoms give off different energy levels, and so the colour of the flame is determined by the difference in the energy levels that the electrons are producing- the level where the electrons are stable and the level where they’re orbiting in high energy. Each atom has different energy levels, so when the electrons are dropping back to their original state, the bigger the difference between the two levels means that the colour in the flame will be brighter but last shorter. The smaller the difference …show more content…
One of those difficulties was taking good photos with the camera. The lens didn’t correctly capture the colours of the flames and displayed them as being large bursts of a block-coloured light. Another difficulty that had been noticeable was the fact that some of the spray bottles had leaked out of the screw-on top or out of the nozzle, resulting in chemicals on people’s hands. The most notable difficulty was that the flame on the bunsen burner would constantly blow out if the chemical was sprayed too close to it and therefore the experimenter would have to turn the gas off, light the match and turn it back on
