What is the molecular shape of HSH

All electrons shown on the left dot and cross diagram. You would expect hydrogen sulfide H2S, to have the same bent V shape and a H-S-H bond angle of ~109o, but due to the greater repulsion of the non-bonding pairs of electrons (lone pairs) the actual H-S-H bond angle is reduced to 92o.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
