Question
Do question 4 please and make your handwriting clear
The identity of the unknown ion is Lithium, Lit. Because, the flame color of an unknown ion is pink.Each element has its own characteristic emission spectrum. From the given data, the only ion that gives a pink color on flame test is Lithium. The principle behind flame test is - when the metal ion is heated, the atoms in it absorb the energy and gets excited to higher energy levels and when they return to the original level, emits energy in the form of visible light. CONCLUSIONS/REFLECTIONS: Please answer the following questiion in the blue box provided. 1. What evidence observed in this lab could be used to support the theory that electrons are found in definite energy levels around the nucleus? 2. Explain how light is emitted when an element gets excited. 3. How might emission spectra be used in studying stars? 4. Why do you suppose that larger elements such as neon produce more color bands (i.e. line spectra) than smaller elements ke hydrogen?
