ANSWER STATEMENT 1 Metal salts emit characteristic color of lights when cooled. 2 Red light has the longest wavelength among the visible lights 3 Microscope is use to analyze the light given by the elements 4 Each color of light has a specific frequency 5 Bohr stated that electrons are moving inside the nucleus 6. The orbits are also known as energy levels 7. Excited state is when the electron received extra energy that it can jump to a lower energy level 8 Atomic orbital is the region around the nucleus where electrons are found 9. The further the energy level from the nucleus, the higher the energy 10. Bohr used mathematical equations to locate the electrons.
