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

ACTIVITY FLAME TEST Summary The purpose of this lab was to see how different compounds can change color while in a flame and with this color‚ I can identify the compound. The test involve putting sample element and see what color appears. Also Thermal excited electron goes from low to high energy level which raises the color but when the excitation ends electron gets to lower level which makes the color back to normal. In order to determine the identity of several unknowns‚ I will perform flame tests
