Question

number of lone pair electron in 20 gm H2S​

Answer 1

Answer:

18

Explanation:

18 is the answer i guess not sure

Answer 2

Answer:

two lone pairs

Their valence electrons are 6. If you will draw their Lewis structures for H2S and H2O, we can see that there are two lone pairs in the central atoms. Based on the molecular geometry table (see reference), both of them have 2 bonding electron pair and 2 lone pairs. They both fall to the group which have the shape bent.
