Which of the following is false? O No two electrons in an atom can have the same four quantum numbers. O Electron spin is a fundamental property of electrons. O All electrons have the same amount of spin. O The orientation of an electron's spin is quantized. O The possible values of spin are +1 and-1.

Suppose hydrogen atoms absorb energy so that electrons are excited to the n (a) n 7 to n =1 (b) n 7 to n = 6 (c) n = 2 to n =1 Enter the letter (a, b, or c) for each Which transition produces a photon with the smallest energy? the highest frequency? the shortest wavelength? 7 energy level. Electrons then undergo these transitions, among others Suppose you live in a ditferent universe where a ditferent set of quantum numbers is required to describe the atoms of that unverse. These quantum numbers have the following rules: N, principal1, 2, 3, L' orbital -N M, magnetic 10,-1 How many orbitals are there altogether in the first three electron shells orbitals A possible excited state for the H atom has an electron in the Sd orbital. List all possible sets of quantum numbers n, E, and me for this electron. (Select all that apply) On- 5, 2, m -2 How many subshells that have a principal quantum number n- 4 exist in the electronic shell?
