Question
(a) List the six possible sets of quantum numbers (n. min ms) of a 2p electron. (Select all that apply.) (2, 1,-1, 1/2) (2, 0, +1, +1/2) (2, 1, 0, 1/2) (2, 1, 0, 1/2) (2, -1, +1, +1/2) (2, 1 1, +1/2) 2, 1, -1, +1/2) (2, 0, +1, 1/2) (2, 1, +1, 1/2) (b) suppose we have an atom such as carbon, which has two 2p electrons. Ignoring the Pauli principle, how many different possible combination of quantum numbers of the two electrons are there? c) How many of the possible combinations of part (b) are eliminated by applying the Pauli principle?Explanation / Answer
for a p electron n = 2, l= 1, m = -1, 0,+1, ms = +1/2 , -1/2
possible sets are : 2, 1, -1, +1/2
2, 1,0, +1/2
2,1,-1,+1/2
2,1,+1, -1/2
2,1,0, -1/2
2,1,0,-1/2
--------------------------------
(b) 15 combinations are possible .
(c) applying Pauli's principal only seven combinations are possible (two electrons with same spin can not stay in same orbital)
-----------------------
8 combinations are eliminated
---------------
Answer is NO ; As two electrons are in different energy level n is different.
