Question
Identify the metal(s) in each of your Unknowns. Unknown 1: ID Code __________ Metal(s) _______ Unknown 2: ID Code __________ Metal(s) _______ Briefly but completely explain how you made these determinations. Which is likely to be the better way to identify an unknown substance - by its physical appearance, or by its emission spectrum? Explain, citing specific examples if possible. Fill in the blanks below to describe what occurs to produce an emission spectrum. When energy is added to atoms (for example by an electrical power supply or a flame), some of the ________ in the atoms _________ energy, which causes them to go from ______________ energy levels to _________ energy levels. Once they have been promoted to __________ energy levels, these __________ are energetically___________, and will spontaneously move (back) to _______ energy levels. When this occurs, that atoms ___________ energy in the form of __________ of electromagnetic radiation. If this energy is visible to us. we call it_______________. Because the electron levels have very specific energies (i.e. they are said to be _____________, the emitted electromagnetic radiation also has very specific values. For visible emissions, this gives a spectrum of specific____, which is unique to that element and can therefore be used to identify it.Explanation / Answer
