This rule is a guide to understanding bonding. In order to become stable, atoms with incomplete outer shells will attempt to join chemically with another atom, and to share the electrons of that atom in its own outer shell, so as to fill it. This is called chemical bonding . Oil Pollution Oil pollution is the degradation of the quality of the water, when crude oil, lubricants, fuel oil, etc. contaminate the aquatic environment. 6p 7s 5f 6d 7p Organic Chemistry Organic chemistry is the study of the chemistry of carbon compounds.
Organic compounds form the chemical basis for life and are more abundant than inorganic compounds .
Carbon compounds are made up of carbon atoms which form covalent bonds with each of its neighboring carbon atoms in either a chain or a ring and also form bonds with other atoms mainly hydrogen, oxygen, nitrogen or sulphur. Compounds containing only carbon and hydrogen are known as Hydrocarbons. Osmosis Osmosis is the passage of a solvent through a semipermeable membrane which acts as a barrier to the passage of the solute dissolved in the solution. The passage of water through the walls of living cells, which consist of very thin membranes that act as a barrier to substances dissolved in the water, is an essential process in living cells and is an example of osmosis. In general, the molecules of the solute are too large to pass through such semi-permeable membranes.
