The Earth's crust consists of the following elements and percentages: # Oxygen--47% # Silicon--28% # Aluminum--8% # Iron--5% # Calcium--4% # Sodium--3% # Potassium--3% # Magnesium--2% # Titanium--0.5% # All others--<1%
94 kinds of atoms occur naturally on earth
There are 118 different kinds of atoms that occur naturally on Earth, known as elements. This is because of the unique number of protons in the nucleus of each atom, which determines the element's identity. The various combinations of protons, neutrons, and electrons give rise to the different elements found in nature.
I wouldn't say that many chemicals occur naturally in the air, however Oxygen and Nitrogen are the two main gases that make up the Earth's atmosphere.
118 total - 92 natural elements= 26 elements that do not naturally occur===========================
There are 118 known chemical elements, of which 92 occur naturally on Earth. These naturally occurring elements include a variety of atoms, ranging from hydrogen (the simplest) to uranium (the heaviest). While some of these elements are abundant, others are quite rare in nature. Each element consists of unique types of atoms that define their chemical properties.

There are 92 naturally occurring elements on Earth. Elements beyond uranium (atomic number 92) are not found naturally, except for trace amounts of some transuranic elements like neptunium and plutonium that are formed in nuclear reactions or decay processes.
There are 118 known elements. The first 92 or so occur naturally.

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.
Radioactive Decay occurs naturally all around us. If you test for radiation with a Geiger Counter, you will find that it picks up radiation in the air around you. Mostly, however, radioactive decay occurs in the earth's crust. I cannot name a specific element, as there are many that decay.
