All the elements between Hydrogen and Uranium, inclusive, except elements 43 and 61: Tc (Technetium) and Pm (Promethium) and even these tow have now been found in nature,
Silver and gold can be found in their elemental state as can Nitrogen, Oxygen, the inert gases etc.
Elements number 1-42, 44-60, and 62-92.
--------
Today 94 elements (1 to 94) are considered natural chemical elements.
118 total - 92 natural elements= 26 elements that do not naturally occur===========================
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.
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.
A Periodic table The Periodic Table of the Elements.
Periodic table comprises of elements. These are arranged in groups and periods.
118 total - 92 natural elements= 26 elements that do not naturally occur===========================
Everything in the Periodic Table up to Uranium (92). Wrong, not everything, the elements Technetium (43) and Promethium (61) do not occur naturally.
Yes, lead is a naturally occurring element. You can find it on the Periodic Table of 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.

Naturally occurring and man made elements
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.
No, as it occurs in naturally occurring elements of the periodic table.
