    if given a question like this
    "According to VSEPR Theory, the H-Te-H bond angle
    in H2Te should be closest to"
    how would u answer it?
    is it asking for molecular or electronic geometry?
    how can you tell?

    umm i would guess the angle to be around 120. The two lone pair of electrons on Te push the hydrogen bonds into a "bent" shape, giving you an angle around 120. Someone chime in if i'm completely off base here...haha

    Hmm i think its bent
    Te has 6 valence e-
    H has 1 valence e-

    H2Te total 8 valence e-

    Te is sp3 hybrid so if all e- were bonded it would be 109.4 but since only two are bonded it would be like water bent.

    haha i guess i was half right with the "bent idea" then. just not right with the angle...120 i think is more for trigonal planar or tetrahedral molecules

    it is bent just like H2O. since TE is in the same group as O it has the O characteristics and therefore, form 120 angle. hope this would help.

    it seems that when the questions says what does vsper say (not mentioning electronic or molecular) you guys assume it is molecular. IS that a correct assumption to make?

    Water is not 120 its 104.5 degrees

    120 is for trigonal planar
