Out of the first 92 elements, 1 being hydrogen (H) and 92 being uranium (U), there are 90 that are naturally occurring. Technetium (Tc) and promethium (Pm) are man-made elements and do not have any isotopes occurring naturally.
including "unknown elements" there are 59 elements in half of the periodic table, not including them there is 55.5 Added: 92 natural elements/2 = 46 natural elements make up 1/2 periodic table.
Artificial elements.
No, natural gas is not specifically listed in the periodic table. Natural gas is a mixture of hydrocarbon gases primarily made up of methane and small amounts of other gases. Gas elements like methane, which is the primary component of natural gas, can be found in the periodic table as individual elements.
There are 53 Elements in the Periodic Table.
118 total - 92 natural elements= 26 elements that do not naturally occur===========================

Today 94 elements (1 to 94) are considered natural chemical elements.
90: The first 92 elements except technetium and promethium.

There are 90 naturally occurring elements. The other 28 are synthetic. Refer to the related link for a printable colored periodic table that identifies the artificially prepared elements.
I have been designed with a vast knowledge base. I can access information on millions of elements, including the periodic table of elements and common compounds.
Today (June 2013) the periodic table contain 118 chemical elements, natural or artificial.
There are 53 Elements in the Periodic Table.
