Working under the presumption that you mean H2Se: Selenium has 6 valence electrons, and each of the two Hydrogen atoms have one. The simplified Lewis dot diagram would look like: H:Se:H and the three dimensional structure would be linear. ========================================== There will be two additional lone pairs represented in the Lewis structure of H2Se, just like for water. Whether you believe that there will be hybridization or not, the hydrogen atoms won't be 180 degrees apart from one another. The bond angle usually reported for H2Se is 91 degrees, which either implies no hybridizaton or a very distorted tetrahedral (sp3) arrangement. Don't be misled by the "linearity" of the Lewis structure.
H2S or hydrogen sulfide has a bent structure. The S is the central atom, with single bonds to both H atoms. and two lone pairs left on the central atom, which makes the compound a tetrahedral.
Hydrogen sulfide (H2S) is somewhat analogous to water (H2O) in its structure. The Hydrogen atoms form bonds to the shared sulfur atom at an angle from each other. The bond angle of H-O-H is 105°, and that of H- S-H is 92°.
Solid SeS2 is a mixture of S8-nSen ring compounds. The ring is 8 membered like sulfur. The amounts of Se in the rings vary to give an overall atomic proportions of Se:S 1:2.
