Flame Test Lab - Post Lab Questions and Pre-Lab Questions
Pre-Lab Questions:
1.When an atom absorbs energy, the electrons move from their normal state to an excited state. When an atom emits energy, the electrons move from an excited state to their ground state and give off photons.
2.Is the flame test a qunatitative test or qualitative test for the identity of an unknown? This flame test is both quantitative and qualitative. It is quantitative because we are measuring the wavelength, and it is qualitative because we are making observations about the color and the chloride.
Post-Lab Questions:
1.) What is happening inside of elements/compounds when they release color to the surroundings? Atoms of each element absorb energy and release as a specific color of light. When the energy is absorbed by the atom, that energy rearranges its electrons from their ground state (lowest energy state) to an excited state (higher energy state), and the extra energy from this absorption is given off as light, and the amount of energy or light given off determines the color.
2.) When you think of color being emitted to you (from energy source) or bouncing off of something to your eyes, you should think of that color as not just color but what? This could be viewed as light and energy, because the wavelength of the light determines the color of it on the visible spectrum.
3.) Why do different things release different colors when burned? Different elements release different amounts of energy when their atoms absorb it, and this difference of energy means a different wavelength on the visible spectrum, therefore changing the color of the elements, explaining why different elements have different colors.
4.) Relate this information to what we can determine about celestial bodies? Different celestial bodies are made up of different substances or elements, and these substances and elements release their own amount of energy which changes their place on the
