Q. If the quantum number for the 5^{th} electron in carbon atoms are 2,1,1,+1/2, then for the 6th electron, these values would be
A) $2,\ 1,\ 0, - \frac{1}{2}$
B) $2,\ 0,\ 1, + \frac{1}{2}$
C) $2,\ 1,\ 1, - \frac{1}{2}$
D) $2,\ 1,\ - 1, + - \frac{1}{2}$
Explanation
(d)
$\ _{6}C = 1s^{2},2s^{2},2p^{2}$
For 6th electron; $n = 2,\ l = 1,\ m = - 1\ and\ s = + \frac{1}{2}$
