Experiment 7: Quantum Mechanics General Chemistry I and II Lab Manual Dakota State University Page 94 of 232 The Aufbau process tells us what subshells (s, p, d, or f) are present in any given shell. Begin by drawing out a diagram of each shell and all associated sub shells with that shell, being very careful to keep consistent spacing both horizontally and vertically. Then draw angled lines through them beginning from the 1 s orbital through the remainder of the diagram. Then simply read off the order of filling beginning from the first line and going through diagonally down each line from the upper right to lower left until you’ve gone as far as needed. From this diagram we see that the order of filling is 1 s 2 s 2 p 3 s 3 p 4 s 3 d 4 p 5 s 4 d 5 p 6 s 4 f 5 d 6 p 7 s 5 f 6 d 7p , which is

Unformatted text preview: as far as the periodic chart goes. Take a careful look at the periodic chart with this filling order and follow it along to see how it corresponds. Once we know the order of filling, we can simply fill in the electrons, remembering of course the number of electrons each element can hold, until weve accounted for all of the electrons in the element, even if we are looking for an element that is beyond those that have been discovered to date! Remembering the number of electrons each subshell can hold, and the subshells present for each shell, fill out the following table for the entire periodic chart. (One example has been included.) Atomic Number Element Symbol Electronic Configuration 1 H 2 He 3 Li 4 Be 5 B 6 C 7 N 8 O 9 F 10 Ne 11 Na 12 Mg...
