Write the electronic configuration and find the no. of unpaired electrons as well as total spin for the following atoms: (i) _(6)C (ii) _(8)O (iii) _(15)P (iv) _(21)Sc (v) _(26)Fe (vi) _(10)Ne

Answer»

Solution :
`THEREFORE` No. of UNPAIRED electrons = 2
`therefore` TOTAL spin `=(+2)/(2)` or `(-2)/(2)`

`[Ar] 3d^(1)4S^(2)`
`therefore`No. of unpaired electrons = 1
`theredore` Total spin `=(+1)/(2)` or `(-1)/(2)`
