Lone pair-lone pair repulsions are greater than lone pair-bonding pair and bonding pair-bonding pair repulsions. The greater repulsion exerted by two lone pairs further compresses the H-O-H bond angle in water molecules. It is much smaller than the ideal tetrahedral bond angle, and the molecular geometry is bent.

Therefore, shared pair (which are 'pulled' by 2 nuclei.) are further away from the central atom nuclei than lone pairs. Because lone pairs are held closer to the nuclei, their repulsion area (area where their charge is felt by other particles) is closer to the bonding pairs. The lone pair orbital will point toward the fourth corner of the tetrahedron, but since that position will be vacant, the NH 3 molecule itself cannot be tetrahedral; instead, it assumes a pyramidal shape, more specifically, that of a trigonal pyramid (a pyramid with a triangular base).

The structure of an SeH₂ molecule resembles that of a water H₂O molecule. Two Se-H bonds connect the three atoms in each SeH₂ molecule. 2010-11-29 electron pairs and their central cations are often referred to as lone pairs and lone pair cations, respectively. Some examples of cations carrying a lone pair are shown in Table 1.1; Sb3+, Se4+ and Te4+ have been utilized in this work.

This accounts for all 26 electrons and gives every atom in the molecule a share in 8 valence electrons, an octet. There are 3 bonding pairs of electrons and 10 lone

p. orbitals. This leads to a highly stereoactive, localized lone pair.

In the hypothetical molecule SeCl2, the central atom Se has two lone pairs of electrons in addition to the two bond pairs in the Se-cl bonds. What is the shape of this molecule?
