118 total - 92 natural elements= 26 elements that do not naturally occur===========================
There are about 30 elements on the periodic table that do not occur naturally on Earth, known as synthetic elements. These elements are created in laboratories through nuclear reactions.
The elements that are placed outside of the periodic table are called transactinides. These elements are usually placed in a separate row below the main table and are synthetic elements that do not occur naturally on Earth.
No, the most naturally occurring elements are not all metals. The majority of elements on the periodic table are metals, but non-metal elements also occur naturally. Examples of non-metals include oxygen, nitrogen, and carbon.
Man has not "made" any eleents, but many of the elements on the periodic table do not naturally occur in their purist form in the crust, and some are so unstable that they can only exist for a few seconds after we have produced them in a reaction.
92 elements occur naturally on the periodic table.

Everything in the Periodic Table up to Uranium (92). Wrong, not everything, the elements Technetium (43) and Promethium (61) do not occur naturally.
Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.

All of the known 118 naturally occurring and synthetic elements are arranged on the periodic table.
All together there are 118 elements on the periodic table, 94 of which occur naturally on earth. http://en.wikipedia.org/wiki/Periodic_table_%28standard%29 They do also show a wide format of periodic table with additional elements that have not been discovered, isolated, or synthesized on earth. http://en.wikipedia.org/wiki/Periodic_table_(wide)
Basically, all (or most) of the elements found in the periodic table, up to plutonium.
No, the most naturally occurring elements are not all metals. The majority of elements on the periodic table are metals, but non-metal elements also occur naturally. Examples of non-metals include oxygen, nitrogen, and carbon.
The first 92 (through uranium) occur naturally. The others are "transuranics." As of 2009, there are 118 ending with ununoctium. All together there are 117 elements on the periodic table, 94 of which occur naturally on earth. According to Wikipedia, there are 117 elements that have been isolated or synthesized, with a gap between element 116 and element 118. They do also show a wide (extended) format of periodic table with additional elements that have not been discovered, isolated, or synthesized on earth. See the related links below to see the standard and extended periodic tables.
