___________ as element is present in sample like charcoal, paper and even in a precious stone like ___________.

__________ compounds are carbon compounds which properties depend on the number of bonds formed. The __________ bonds found in organic or carbon molecules are formed by __________ of electron pairs between atoms. The primary bond that holds between carbon atoms is sigma bond, while the multiple bond (double or triple) formed by __________.

Atoms with four (4) or more valence electrons like carbon form as many bonds as they need electrons to fill their valence shells and thereby reach a stable __________.

It is important to always count the number of bonds of each particular atom. Carbon should have __________ bonds. Hydrogen has only one (1) bond, oxygen with two (2) bonds, nitrogen could have __________ bonds, and only one (1) bond for halogens.

Carbon, oxygen and nitrogen, with more than one bond, could possibly formed ___________ bond (double or triple bond).
