Lone-pair electrons, Bonded pairs of electrons
Pairs!
Homologous pairs are called tetrads because these pairs are maid up of a four-part structure. Tetrad literally means a group of four.
Some molecules (not just ionic compounds) always tend to come in pairs. Aluminum oxide for example Al2O3 always comes in a pair Al4O6, the empty electron pairs on the Aluminum making attractive sites for the filled electron pairs on Oxygen to 'stick' to.
NH3's shape is trigonal pyramidal, which has 1 e lone pairs and 3 bonding pairs, while BH3's shpe is trigonal planar, with 0 e lone pair and 3 bonding pairs. It's the force that electron lone pairs exert that pushes the molecules further and the repulsion force of lone pairs that aided in changing the shape of the molecules. Hence, the shape are different ...

what pair is considered the major plasma buffering system
\gene
Yes, they do. If a+bi is a solution, a-bi is also a solution.
Ammonia NH3 one lone pair on Nitrogen, Water H2O two lone pairs on Oxygen.

CFC's result in ozone destruction. They react with ozone and deplete it.
