An atom has 2K and 8L electrons write down its electronic configuratio

1.	An atom has 2K and 8L electrons write down its electronic configuration and indicate 1) total number of subshelld2) total number of orbitalsPlease answer fast and don't spam otherwise I'll report.
Answer» 8Explanation:The number of electrons in the shells is given as 2 in K shell, 8 in L shell and 5 in the M shell. Thus, the atom has in total of 2+8+5 = 15 electrons. Hence, the atom is phosphorus.The electronic configuration will be as FOLLOWS : 1s 2 2s 2 2p 6 3s 2 3p 3 Number of unpaired electrons = 3 (3p x 3p y 3p z ) The three unpaired electrons are in the 3p x , 3p y , 3p z ORBITALS respectively.Hence, option (B) is correct.solution
