1.	The electronicconfiguration, groupnumberandperiodnumberof anelementwithatomicnumber10 is
Answer» Solution :Itselectronicconfigurationis ` 1 s^2\| 2s^22p^22p^6= ( 2.8 )` thismeansit contains2 electronsin K- shelland8electronsin Lshell Itsperiodnumber= no .Of shells=2 itsgroupnumber= No.ofvalanceelectrons`+ 10= 8 +10` =18 [Ifnumberof valanceelectronsis morethan2groupnumber= numberof valenceelectrons+ 10]
