IV. There is one more policy that helps the hotel run smoothly and keep customers happy. Hund's Rule states that if electrons are being placed in the same section of a floor (rooms that cost the same) then each one gets their own room and has the same spin until the floor is half-filled. If any more electrons want to stay in that same section, then they must pair up with another electron and assume the opposite spin. This does not necessarily apply to electrons that have purchased more expensive rooms. In the diagrams below identify the areas in which Hund's Rule was broken. Describe how the rule is being broken in each case. 12 February 12, A 1L 1L 1L 12 12 [16] 14 November 26, B 1 14 14 14 14 14 14 July 10, 1983 C

Erwin Schrödinger Solution of the Schrödinger wave equation for the hydrogen atom results in a set of functions (orbitals) that describe the behavior of the electron. Each function is characterized by 3 quantum numbers: n, I, and m, n is known as the I is known as the m, is known as the n specifies / specifies my specifies 0 quantum number. quantum number. quantum number. A.The subshell-orbital shape. B.The energy and average distance from the nucleus. C.The orbital orientation.

Predict the total electron spin for P.

Which of the following statements is FALSE? An orbital that penetrates into the region occupied by core electrons is more shielded from nuclear charge than an orbital that does not penetrate and therefore has a lower energy. Two electrons in the same orbital cannot have the same spin. An orbital that penetrates into the region occupied by core electrons is less shielded from nuclear charge than an orbital that does not penetrate and therefore has a lower energy. None of the above is false. It is not possible for two electrons in the same atom to have identical values for all four quantum numbers.
