A) 12, 13
B) 13, 14
C) 10, 11
D) 11, 12
Correct Answer: D
Solution :
If \[n=3,\text{ }l=0,\,w=0\]then the electronic configuration may be as follows: \[1{{s}^{2}},2{{s}^{2}}\text{ }2{{p}^{6}},3{{s}^{1}}\text{ }or\text{ 1}{{s}^{2}},\text{ }2{{s}^{2}}\text{ }2{{p}^{6}},3{{s}^{2}}\] Hence, the probable atomic numbers are 11,12.You need to login to perform this action.
