Question

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 1

`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)`
