How old are puppies when they open their eyes. I would like to know how old mini schnauzer puppies are when they open their eyes. Optional Information: Age: <1; Male; Breed: mini schnauzer. Submitted: 10 years ago.
The central Sn atom is bonded to the three Cl atoms and has one nonbonding pair on it. Therefore, the Sn atom has four electron domains around it. The resulting electron-domain geometry is tetrahedral (Table 9.1) with three of the corners occupied by the bonding pairs of electrons.
Basically, electron pairs in a molecule want to adopt a geometry to maximize their distance apart, since like charges repel each other. For example, methane (CH4) adopts a tetrahedral arrangement - you can think of this as the carbon atom at the center of a pyramid and the 4 hydrogens at the four vertices. Bonds angles are 109.5 degrees. This is a case where all electrons are bonding electrons; they form the 4 bonds between carbon and hydrogen. Lone electron pairs also affect the geometry. For instance, water (H2O) has two lone electrons pairs; it adopts a bent/angular geometry.
