Fireworks Research Paper

5)A spectroscopy would provide the different colours of the stars that make up the colour to be seen by the naked eye. It would provide the energy level that is made up in the star and would also tell astronomers what elements a certain star is made of.

6)Electrons in the Bohr theory are in perpetual motion, which says the electrons are constantly accelerating and decelerating. As the electrons are moving inward and outward they are moving through different energy levels, known as orbitals. In order to move through the different energy levels, electrons gain or lose energy to become like it noble gas representative. They gain energy through heat or through collisions, and they lose energy by emitting light.

7)“Spectral lines are the fingerprints of elements.” This means that the spectral lines are used to identify elements by the colours they are assigned, every element is unique. Each element has a different set of spectral lines to work as a “fingerprint” to reveal its identity.
Different types of fireworks would have different elements or compounds in them. b.) If you wanted red fireworks, you could use lithium nitrate or lithium chloride. For orange, use potassium nitrate, calcium nitrate or sodium nitrate. For yellow fireworks use barium nitrate. If you wanted green fireworks use copper II nitrate or copper II chloride. Limitations to compounds you can use in fireworks is you need to make sure they are not toxic, so certain colours may not be
