What is the de Broglie wavelength of an electron traveling at a 3.51×106 m/s? The mass of an electron is 9.109 × 10–28 g. λ = m Determine whether each set of quantum numbers (n, l, ml, ms) below is possible or not possible. (5, 2, −2, +½) is a set of quantum numbers. (3, 3, 2, +½) is a set of quantum numbers. (4, 1, 0, −½) is a set of quantum numbers. (7, 4, −3, −½) is a set of quantum numbers. Enter the full ground state electron configuration for each element given below. For superscripts, use the ^ symbol before the number. For example, 2s2 should be entered as 2s^2. Add a space between sublevels. For example, 3s23p3 should be entered as 3s^2 3p^3. Be sure to list the subshells in order of increasing energy. Nickel: Tin: Copper: Enter the abbreviated ground state electron configuration for each element given below. Enter the noble gas core with brackets. For example, helium should be entered as [He]. For superscripts, use the ^ symbol before the number. For example, 2s2 should be entered as 2s^2. Add a space between sublevels. For example, 3s23p3 should be entered as 3s^2 3p^3. Be sure to list the subshells in order of increasing energy. Gallium: Bismuth: Einsteinium:
