As of 2009, there are 118 elements on the periodic table. Of those, 92 occur in nature. The others are artificially created.
Yes, the halogens did occur in nature as free elements.
All elements that occur in nature occur on Earth, the Sun, and the Moon - but the proportions are different. The main difference is that the Sun is made up mainly of hydrogen and helium; both are relatively scarce on Earth and on the Moon.

Any element above Uranium in the periodic table of elements is too unstable to occur in nature.
The weighted average for all isotopes that occur in nature for an element is its atomic weight listed on the Periodic Table of the elements.

All elements between and including Neptunium (Np) up to the element Ununoctium (Uuo) are not remnants of fusion and do not occur naturally on earth.

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)
Most elements on the Earth occur as oxides or silicates.
