If n = 3, l= 0, m = 0, then atomic number is – InterviewSolution

1.	If n = 3, l= 0, m = 0, then atomic number is
Answer» 12 or 13 13 or 14 10 or 11 11 or 12 Solution :n = 3, l = 0 means last shell is 3s. `therefore` ELECTRONIC configuration will be `1s^(2)2s^(2)2P^(6)3s^(1-2)` ATOMIC number is 11 or 12.
