Talk:High School Chemistry/Electrons and Light

Quiz
{In 1900s, scientists found out that different elements made different colored-flames. What can be observed from this? - Protons and neutrons both cause these different colors. - This never happened. + The arrangement of electrons determine the different colored-flames. - It depends on the electron's atomic mass.
