Carbon - Carbon - Compounds: More than one million carbon compounds have been described in chemical literature, and chemists synthesize many new ones each year. Much of the diversity and complexity of organic forms is due to the capacity of carbon atoms for bonding with one another in various chain and ring structures and three-dimensional conformations as well as for linking with other atoms.
While there are many thousands of different chemical compounds there is a very definite system of nomenclature whereby we can name or write chemical formulas for most compounds. We divide the compounds into two main types – binary compounds and ternary compounds. Binary Compounds . All true binary compounds contain only two elements. The chemical formula gives us a clear understanding regarding the chemical substances, like how many and what the chemical elements of the Periodic table consists of, along with the way they are arranged. There are about some chemistry formulas coming in the chemistry as given below. The other answers explain the ion nomenclature well, but they miss the general rule. Chemists are lazy, if they can simplify a compound while it still only refers to one possible compound, then they simplify the name.
