An electron in an atom is inthen 3 quantum level.a)List the possible values of l,and mithatitcan have, and b) determine the number of orbitals and electrons and c)write the unique quantunm address for each of the electrons in the 3p orbital. (3 pts) Solution a) l can take all values from 0 to n-1 So, l can be 0, 1, 2 for l=0, ml can be 0 for l=1, ml can be -1, 0, +1 for l=2, ml can be -2, -1, 0, +1, +2 b) for given n, number of orbitals = n^2 = 3^2 = 9 each orbital can have 2 electrons So, number of electrons = 2*9 = 18 Answer: 9 orbitals 18 electrons c) for 3p orbital, n=3 and l=1 ml can be -1,0, 1 So, possible values are: 3, 1, -1, +1/2 3, 1, -1, -1/2 3, 1, 0, +1/2 3, 1, 0, -1/2 3, 1, +1, +1/2 3, 1, +1, -1/2 .
