∙ 8y agoAs of 2015, there are 23 man made elements. Technetium (atomic no 43) is the only man-made element that comes before uranium (92), the heaviest natural element.
Scientists have made 22 transuranium elements.
There are a further 4 - Ununtrium (113), Ununpentium (115), Ununseptium (117) and Ununoctium (118) - whose existence has been claimed. However, these are not yet recognised by International Union of Pure and Applied Chemistry (IUPAC).

Man use these things to make things.
Nothing man made makes itself.

Are most elements man made or natural?
All the existing elements are natural the man made elements are rare and have a very short life.
How many naturally occurring atoms exist?
well buddy there are only 92 elements in the periodic table occurring naturally on earth.. the rest are all man made...
Are man made elements stable?
Yes they are everything around you is man made.
Total no of elements known to man?
112 Elements ( 92 Natural and 20 Man-made ) .
How many elements are made by man from the periodic table?
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.
Elements that occur somewhere on earth are what?
The planet Earth and everything on it, including us, is composed of the chemical elements. Not only are elements found on Earth, but everything found on Earth is made of elements.
Is potassium man made or made of earth?
Potassium is one of the elements.
What does the earth element's are considered?
All the elements on the earth (excepting of course man made elements) are considered natural chemical elements.
How many naturally occurring elements are (were) there on earth?
92 are natural occuring, other remaining are man made.
How many man made elements are in the periodic table?
Out of the 112 elements known, 90 are found in nature and the rest (22 are man made).
How many are man made elements of the 118 known elements?
The 26 transuranic elements (elements with atomic numbers higher than 92) are man-made. Some lists also count technetium (element 43) as man-made as well. --------------- Now (January 2013) 97 chemical elements are considered as natural and 21 as man made.
How do you make man made elements?
Man-made elements are made in a particle accelerator.
Is it real that 92 elements are found on earth?
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.
What man made object orbits the earth?
is helium a man-made element?man made elements are elements which come after uranium U92.elements after this do not exist in nature.they are created by bombarding heavy elements like uranium.the list of man made elements are:-neptuniumplutoniumamericiumcuriumberkeliumcaliforniumeinstineiumetc.
Are man made elements important in health and medicine?
Yes but many of them are harmful to both man and plants...
Satellite of earth?
A satellite of earth that is not man made is the moon. There are many satellites that are man made that orbit the earth. These satellites are used for communication between Internet and television viewing.
Are most elements man made or natural?
All the existing elements are natural the man made elements are rare and have a very short life.
