Question

variable valency of phosphorous in first excited state
variable valency of sulpher in 2nd excited state is​

Answer 1

Answer:

The valence shell electron configuration of ground state of sulphur is 3s

2

3p

4

The valence shell electron configuration of first excited state of sulphur is 3s

2

3p

3

3d

1

The valence shell electron configuration of second excited state of sulphur is 3s

1

3p

2

3d

2

.

This is followed by sp

3

d

2

hybridization to form SF

6

. Thus SF

6

is formed in the second excitation state of sulphur atom.
