The henry Atom Spectrum Evan J. Collins C. N. push-down storage June 16, 2009 INTRODUCTION MATERIALS _Emission Spectra an the Electronic Structure of Atoms_ spectroscope Black Ink Pen black lead Pencil Notebook Mercury Spectrum Hydrogen Spectrum PROCEDURE standardisation of the Spectroscope development the spectroscope the four most megascopic lines on the scale were measured. Violet, blue, green, and yellow were tout ensemble visible. With the ink pen the measurements were recorded. A know wavelength (nm) vs. measured lines (cm) graph was whence worn from the measurements.Observation and Measurements of the Hydrogen Spectrum Using the adjust spectroscope the scale position of the apparent lines of the hydrogen emission spectrum were measured. Red, turquoise, violet, and purple were all in all visible. Using the measurements and the calibration graph the wavelength of the lines were determined. The relational error was mensurable using evaluate Value Values of wavelength for the hydrogen mote spectrum were converted to kJ/ counterspy. Using a physical body of the Rydberg equation, the Rydberg constant was calculated for each of the lines measured.This constant was used to then calculate percentage error. Data Calibration of the Spectroscope Observations and Measurements of the Hydrogen Spectrum CALCULATIONS (Convert wavelength values to like energy in kJ/mol) 680 x 10-9 2. 92 x 10-19 J x (6. 022 x 1023) / (1000 J) = 176 kJ/mol (Calculate the value of the Rydberg constant) (1/680)/(. 25-. 30) = . 00147059/(. 25000-. 11111)= 0. 0105042 x 10-7 = Rh= 105,040 cm -1 (Calculate Percentage Error) 105040 109678 X 100 = 4. 23% Error 109678 give-and-take/CONCLUSION
