Water (H 2 O) - Water has two hydrogen atoms bonded to oxygen and also 2 lone pairs, so its steric number is 4.; Ammonia (NH 3) - Ammonia also has a steric number of 4 because it has 3 hydrogen atoms bonded to nitrogen and 1 lone electron pair. For example, if SnCl2 is added dropwise into a solution of mercury(II) chloride, a white precipitate of mercury(I) chloride is first formed; as more SnCl2 is added this turns black as metallic mercury is formed. Follow this trick and you'll be able to solve any bond angle comparison problems. To get the Lewis Structure, add 3 lone pairs of electrons around each Cl & 2 lone pairs of electrons to I (for a total of 28e-). 10-8= 2e-= 1 lone pair. The one lone pair on the top has greater repulsion than the bonding pairs, as a result the normal tetrahedral angle which is 109.5 is reduced to 107 (-2.5). • 2H2O.
