Givethenameand atomicnumber of theinertgas atomin whichthe totalnumber

1.	Givethenameand atomicnumber of theinertgas atomin whichthe totalnumberof d- elementis equal todifference innumberif totalp- ands-electrons.
Answer» SOLUTION :The firstinert GAS whichcontainsd- electrons is krypton. Itsatomic numberis 36and itselectronicconfigurationis `: 1s^(2)2s^(2)p^(6)3s ^(2)p^(6)3 d^(10)4 s^(2)4p^(6)` LTBGT Totalnumber ofd- electrons = 10 Total numberof - electrons= 6+6 += 18 Totalnumber ofs- electrons= 2+ 2 + 2 +2 = 8 `:. ` Differencein totalnumberof p - ands- electrons = 18 - 8 = 10 . Thus the INERTGAS iskrypton.
