Question

Draw the Lewis structure for SeS₃ and answer the following questions.

How many valence electrons are present in this compound?

How many bonding electrons are present in this compound?

How many lone pair (non-bonding) electrons are present in this compound?

What, if anything, is wrong with each of the following structural representations of SeS₃?

(Only the lone pairs on the central atom are shown. Assume the double bonded atoms have two lone pairs and the single-bonded atoms have three lone pairs.)
nothing is wrong too many electrons used too few electrons used incomplete octet about the central atom  SeS3F2
nothing is wrong too many electrons used too few electrons used incomplete octet about the central atom  SeS3T
nothing is wrong too many electrons used too few electrons used incomplete octet about the central atom  SeS3F1
