Today 94 elements are considered natural chemical elements.
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)
Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.
There are 118 elements arranged on the periodic table.
In the Periodic Table of Elements there are: 118 Observed Elements 114 Officially Discovered Elements 112 Officially named Elements 92 Naturally Occuring Elements 83 Non-radioactive elements
Yes, lead can occur naturally in its pure state in the form of the mineral known as galena. However, it is more commonly found combined with other elements in ores such as lead sulfide or lead carbonate.
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.
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.
All of the known 118 naturally occurring and synthetic elements are arranged on the periodic table.

Basically, all (or most) of the elements found in the periodic table, up to plutonium.
Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.
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.
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.

Hydrogen is the most abundant element in the universe and is naturally occurring. However, most of the hydrogen used by humans is produced through industrial processes such as steam methane reforming or electrolysis of water.
Periodic table comprises of elements. These are arranged in groups and periods.
