Atomic Line Spectra

Cards (9)

  • EM spectrum is CONTINUOUS; Atomic Line Spectra is NOT CONTINUOUS leading to specific colored lines.
  • Electric discharge EXCITES gas atoms, transferring energy to the electron; When an electron is RELAXED, drops to a lower energy level leading to LIGHT emission.
  • The Atomic Line Spectra is NOT CONTINUOUS leading to specific colored lines.
  • The series of colored lines means, the line spectrum IS the atomic spectrum
  • The EMISSION of light is at SPECIFIC WAVELENGTHS, meaning that the atomic spectrum is specific to a SPECIFIC ELEMENT.
  • The Tungsten (W) filaments are found in OLD lights = SMALL percentages of light are available.
  • In the Hydrogen Line Spectrum, Hydrogen has 1 PROTON and 1 ELECTRON, meaning there are several observable lines - visible, UV, and IR regions.
  • If Hydrogen has 1 ELECTRON, 

    then it must explain how this ONE subatomic particle has several lines
  • The Rydberg Equation calculates the lines of the Hydrogen atom. The formula below is: (n - BOTH positive integers, R∞ = 1.09 x 10^7m-1) 1/λ=1/λ =R(1/n121/n22) R∞ (1/n1^2 - 1/n2^2)
