Accel Chem ? Review Sheet: Electronic Structure of Atoms List the four characteristics of a wave needed to define it: List three forms of energy that can cause an atom to emit light: Explain the difference between fluorescence and phosphorescence? As wavelength increases, frequency As frequency increases, energy As wavelength increases, energy As energy decreases, frequency Which color of the rainbow (visible light) has the: highest energy: shortest wavelength: highest frequency: Rank the following from shortest wavelength to longest: microwave, radio wave, gamma radiation, infrared radiation, red light, X-rays, violet light, ultraviolet radiation Describe what is meant by the ?wave-particle duality of light?. What is the wavelength of EM radiation having a frequency of 5.00x1012 Hz? What is the frequency of EM radiation having a wavelength of 3.33x10-8 m? What is the energy of a photon of light with a wavelength of 1.5x10-3 m? What is the energy of a photon of red light with a frequency of 4.48x1014 Hz? Explain what ?the energies that an atom or electron can have are quantized? means. How did the flame tests, spectrum tubes, glow sticks, and fluorescein show that the energy matter absorbs and emits is quantized? Why do atoms only emit a bright line spectrum rather than a continuous spectrum? Calculate the wavelength of light released as an electron falls from the 5th to the 2nd energy level in a hydrogen atom. Explain the relationship between an absorption spectrum and an emission spectrum? Complete the table: Sublevel Number of orbitals Total electrons in sublevel s p d f Name and describe what each of the following quantum numbers describes about an electron: n l ml ms Determine if the following sets of quantum numbers are possible. If not explain why. (n, l, ml, ms) 1, 0, -1, +½ 4, 2, -1, -½ 3, 2, 2, -¾ 0, 0, 0, +½ Write orbital notation for the following atoms: F Si Write complete electron configurations for the following atoms: K P Ni Write the shortened electron configuration for the following atoms and ions: Ge Fr As S2- Al3+ Ce Determine what is incorrect in each of the following electron configurations: 1s22s23s2 1s22s22p73s23p3 1s22s22p63s63p5 1s22s22p63s23p63d2 [Ne]2s2 Determine which element is represented by the following electron configurations: 1s22s22p63s23p4 [Ne]3s23p5 [Xe]6s1 1s22s22p63s23p64s23d5 [Rn]7s2
