Quiz edit

  

1 In 1900s, scientists found out that different elements made different colored-flames. What can be observed from this?

This never happened.
The arrangement of electrons determine the different colored-flames.
Protons and neutrons both cause these different colors.
It depends on the electron's atomic mass.
