The oxidation number and the electronic configuration of sulphur in `H_(2)SO_(4)` isA. `+4, 1s^(2)2s^(2)2p^(6)3s^(2)`B. `+2, 1s^(2)2s^(2)2p^(6) 3s^(2)3p^(2)`C. `+3, 1s^(2) 2s^(2)2p^(6)3s^(2)3p^(1)`D. `+6, 1s^(2) 2s^(2) 2p^(6)`

Answer» Correct Answer - D
`H_(2) overset(**)(S)O_(4)`
`2xx(+1)+x+4xx(-2)=0`
`+2+x-8=0, x=8-2=+6`
Electronic configuration of sulphur in `H_(2)SO_(4)` is
