Photogray lenses incorporate small amounts of silver chloride in the glass of the lens. When light hits the AgCl particles, me following reaction occurs: AgClhvAg+Cl The silver metal that is formed causes the lenses to darken. The energy change for this reaction is 3.10 102 kJ/mol. Assuming all this energy must be supplied by light, what is the maximum wavelength of light that can cause this reaction?
Give the maximum number of electrons in an atom that can have these quantum numbers: a. n = 4 b. n = 5, ml = + l c. n = 5,ms = +12 d. n = 3, l = 2 e. n = 2, l = 1
Assign a correct set of four quantum numbers for (a) Each electron in a nitrogen atom. (b) The valence electron in a sodium atom. (c) A 3d electron in a nickel atom.
One bit of evidence that the quantum mechanical model is correct lies in the magnetic properties of matter. Atoms with unpaired electrons are attracted by magnetic fields and thus are said to exhibit pararamagnetism. The degree to which this effect is observed is directly related to the number of unpaired electrons present in the atom. Consider the ground-state electron configurations for Li, N, Ni, Te, Ba, and Hg. Which of these atoms would be expected to be paramagnetic, and how many unpaired electrons are present in each paramagnetic atom?
