BrF₃ has five electron domains (three bonding pairs and two lone pairs) around the central bromine atom. The lone pairs occupy equatorial positions, resulting in a T-shaped molecular geometry.

IF₅ has five bonding pairs and one lone pair around the central iodine atom, resulting in the VSEPR notation AX₅E and a square pyramidal shape.

IF₄^- has six electron domains (four bonding pairs and two lone pairs) around the central iodine atom. The lone pairs occupy opposite positions, resulting in an octahedral electron-domain geometry and a square planar molecular geometry.

H₂O has two lone pairs on the oxygen atom, which exert strong repulsive forces, reducing the H-O-H bond angle to about 104.5°.

NH₄⁺ has four bonding pairs and no lone pairs around the central nitrogen atom, resulting in both a tetrahedral electron-domain geometry and a tetrahedral molecular geometry.

CO₃^2- (carbonate ion) has three bonding pairs and no lone pairs around the central carbon atom, resulting in a trigonal planar shape.

XeF₄ has six electron domains (four bonding pairs and two lone pairs) around the central xenon atom. The lone pairs occupy opposite positions, resulting in a square planar shape.

SO₂ has a bent shape due to the lone pair on sulfur, resulting in a net dipole moment and making the molecule polar.

NH₃ has a lone pair that exerts a greater repulsive force than bonding pairs, reducing the H-N-H bond angle to about 107°.

PF₅ has five bonding pairs and no lone pairs around the central phosphorus atom, resulting in a trigonal bipyramidal molecular geometry.
