Want this question answered?
well buddy there are only 92 elements in the periodic table occurring naturally on earth.. the rest are all man made...
Total 108 elements are found in earth till 2007 dec 56 to 72 elements are in the human body, 22 to 36 are in the animal body 18 22 elements in birds are found
The Earth is a naturally occurring magnet (it has a north and south pole. The mineral magnetite is also magnetic.
During radioactive decays heat is released.
By the middle of the 1800's, about 60 elements have been discover
90
These elements exist also naturally - in infinitesimal amounts - in the Earth crust.But practically are artificial elements.
92 are natural occuring, other remaining are man made.

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.
Creation of synthetic elements in the laboratory is not based on nuclear fusion.
Synthetic elements are those elements that are not naturally occurring on earth, but rather have been synthesized in a nuclear reactor. They are often radioactive with short halflifes.
