In total, 118 elements have been characterized as of March 2010, and new elements of higher atomic number are "discovered" from time to time, as new synthetic products of artificial nuclear reactions. Of the known elements, the first 92 occur naturally on Earth. Of these, oxygen is the most abundant element in the Earth's crust. About 80 elements have stable isotopes: namely all elements with atomic numbers 1 to 82, except elements 43 and 61 (technetium and promethium). About half of the 80 stable elements are expected to be radioactive with such long half lives that their decay happens only in theory, and is too slow to have yet been detected by experiment (see the list of nuclides). These elements (such as bismuth, only recently measured as unstable) have half lives at least 100 million to 1000 million times longer than the estimated age of the universe.

No doubt, information is the highway to greatness in life. In a bide to obtain such information one is forced to get it whenever it appears online. One is please and satisfy with the rate of such information transfer if it is very fast. But the reverse is case when the data transfer ( i.e. bits or bytes per second ) is very slow.
