an Review In a technique used for surface analysis called auger electron spectroscopy (AES), electrons are accelerated toward a metal surface. These electrons cause the emissions of secondary electrons (called auger electrons) from the metal surface. The kinetic energy of the auger electrons depends on the composition of the surface. The presence of oxygen atoms on the surface results in auger electrons with a kinetic energy of approximately 525 eV Recall that KE = mv %3D and that 1 electron volt (eV)- 1.602 x 10-19 J Part A What is the de Broglie wavelength of this electron? Express your answer in meters to three significant figures. ? m

Absorbance measurements are made on two copper (II) sulfate solutions. One is 0.20 molar and the other is 0.40 molar. The measurements are made using identical path lengths. Which solution will absorb less light? Explain your answer. 0.20 M because its lower concentration results in more light being transmitted. 0.40 M because its higher concentration results in more light being transmitted. O 0.40 M because its higher concentration results in less light being transmitted. O 0.20 M because its lower concentration results in less light being transmitted.
The energy, wavelength and frequency of an emitted photon are all related to the size of the electronic transition (high → low energy levels) occurring in the metal cation. Based on your observations, in which metal did the smallest electronic transitions occur? Briefly explain your response.
Imagine a universe where there are three spin states for the electron instead of two (for example, spin up, spin down, and spin cray-cray). The number of subshells per shell and number of orbitals per subshell stay the same, but an orbital now holds three electrons instead of two. The names of the elements stay the same. Draw the top three rows of what this new periodic table would look like, indicating which elements are in which groups in our new universe, and show the electron configurations of each of the elements of these three rows.
