Pame Tuner Ne In chemistry the occasionally uses a flame test to determine the presence of certain chemical we put a small spoon with sodium in toate bune flame just above the tip (T-1500 K) it will glow with a characteristic yellow color. In this problem we work out about how many stoms of sodium are response for what we see. We'll sure that as the sodium is heated, collisions with hot molecules drive the outermost lectron of some of the sodium op from ground state (labeled 3s) to its first excited state (labeled 3p). The flame and the energy levels of the least bound electron in sodium are shown in the figure at the right. (Don't worry about the complexity of the diagram, we only need the two levels involved in the 3p3s transition indicated by the yellow row.) A. The wavelength of the yellow light emitted by the 3p3s transition in sodium 500 mm. What is the energy of the emitted photon? Submit Answ Tries 0/09 B. The probability of finding an atom at an excited state (elative to the probability of finding the atom in the ground state given by Pratcom temperature ( 300 ), what is the relative probability compared to being in the ground state that a sodium som i ledtron excited up to the state? Pap/Pss- Submit Answer Tries 0/99 C. At the temperature of the fame T 1500 K), what is the probability that a sodium atomhas its dectron excited up to the State? Pje/ Sub Answer Tries 0/99 D.
