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.
Yes! Out of the current 118 known elements 92 of them are natural occurring, and 26 are man made. Only 90 of the 92 natural elements are found on Earth. The other 2 natural elements are found in space.
Usually it is erosion by natural elements (wind, rain, excessive water), or chemicals (natural chemicals will break down all elements in a matter of time).

i think there are 3 elements hydrogen; sulfur; and oxygen
there are 51 natural elements we know of
Today 94 elements (1 to 94) are considered natural chemical elements.
92
Now (2013) are considered as natural chemical elements 97 elements (including berkelium).
90: The first 92 elements except technetium and promethium.

Usually two : carbon & hydrogen.
There are many more than three elements that are solid under standard conditions.
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.
No. There are 92 natural elements.
In theory, all elements are naturally made, but many of the large ones have decayed into smaller elements over billions of years
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.
