No, only the elements up to Uranium (Z=92) occur naturally on Earth. The rest have only been made synthetically, because of their radioactivity which renders them unstable and thus unable to exist naturally. The synthetically made elements are called transuranic elements.

∙ 11y agoOf the first 92 elements in the Periodic Table, only 90 are found in nature. The two "holes" belong to the elements with atomic numbers 43 (technetium, Tc) and 61 (promethium, Pm). These two elements have only radioactive varieties (isotopes), all of which decay away in relatively short times on a geologic scale. There are no stable forms of either.

∙ 13y agoI would believe that it is about 85% of the 112 elements occurs in nature.
90, technetium and promethium are radioactive with short halflives, they do not occur naturally.

How many known elements are there on earth are naturally made?
92 elements occur naturally on the earth.
How many elements are found in the ocean?
98 elements are known to occur naturally on earth. They are probably all found, at least in some minute fraction, in the seas of the world.
How many elements do not occur in nature on earth?
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.
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 it true that on earth 90 elements occur naturally?
Yes, at least 91 elements occur naturally: all of those with atomic numbers of 92 or less except technetium. This still means that the problem "statement" is true, because it does not contain any limiting word such as "only" to modify the number 90. (It is equally true that 2 elements occur naturally.)

How many elements do not occur in nature on earth?
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.
Which two actinides occur naturally?
Uranium and Plutonium are the only elements from the Actinides series that occur naturally on Earth, though they are rare.
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.
How many elements start naturally in nature?
how may elements occur naturally in nature
Is it true that on earth 90 elements occur naturally?
Yes, at least 91 elements occur naturally: all of those with atomic numbers of 92 or less except technetium. This still means that the problem "statement" is true, because it does not contain any limiting word such as "only" to modify the number 90. (It is equally true that 2 elements occur naturally.)
Are all the elements naturally occurring manmade or both?
Not all the elements occur naturally; some elements are man-made.
How many naturally occurring elements are found on earth?
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
How do most elements on earth occur?
Most elements on the Earth occur as oxides or silicates.
