There are currently 118 elements, ranging from #1 Hydrogen to #118 Ununoctium. Many of the transuranium elements (#93-#118) are synthetic, meaning that the only place they have been found is in a laboratory, thus do not exist in nature. Technetium (#43) and Promethium (#61) are also synthetic.
There are 118 elements are found in nature.
92 as traces of technetium and promethium have fairly recently been found in Nature.
If you check factmonster.com , 90 elements were found in nature
There are 88.
92
They are not found in nature. They have only been found in labs, when certain elements were fused using an accelerator. Scientists aren't even sure of their existence as they have only been witnessed for less than a second.
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.

The only way any element heavier than iron can be created in nature is in the stupendous heat and pressure generated by a "supernova" - the explosion of a giant star. Some very heavy new elements have been created in the laboratory in scant amounts (some last only a few milliseconds), but these do not occur in nature.
Fermium doesn't occur naturally, and has not been found in the earth's crust
There are variety of such elements. They have not been found on earth's surface.

There are about 118 different elements that are currently included in the Periodic Table. There have also been elements that have been found in nuclear and laboratories accelerators.
They are not found in nature. They have only been found in labs, when certain elements were fused using an accelerator. Scientists aren't even sure of their existence as they have only been witnessed for less than a second.
Homosexuality doesn't occur in "cases." It's part of human nature, and has been around as along as humans have been around.
All the elements between Hydrogen and Uranium, inclusive, except elements 43 and 61: Tc (Technetium) and Pm (Promethium) and even these tow have now been found in nature, Silver and gold can be found in their elemental state as can Nitrogen, Oxygen, the inert gases etc.
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.
9290, technetium and promethium are radioactive with short halflives, they do not occur naturally.Of the 118 elements that are known, 94 occur naturally. The elements that do not occur on earth naturally, have been produced artificially. Some of the elements that do not occur on earth naturally have been detected in other parts of the universe. See link for more information.Tc and Pm of number 1-92 had not been found naturally until fairly recently, but now they have. Promethium, technetium, neptunium and plutonium are now considered natural chemical elements as trace quantities have been found in nature; consequently, 94 natural chemical elements.We know today there are 118 elements total. So far.94 are considered natural elements as we can add promethium, plutonium and neptunium to natural elements because these elements exist in nature in ultratiny trace quantities.About thirty native elements are known to occur naturally, by themselves, in pure form, uncombined with other elements into minerals. They include metals like copper, gold, lead, and iron; semi-metals like antimony, arsenic, bismuth, and tellurium, and non-metals like diamond, sulfur, and selenium.Some elements decay into other elements very quickly and very little of them remain. However they can be produced in laboratories and during supernova explosions.90, technetium and promethium are radioactive with short halflives, they do not occur naturally.Astatine has an even shorter half life, being furiously radioactive. Make it 89 ?90 elements out of the first 92 elements are naturally occurringThere are 88 naturally-occurring chemical elements90, technetium and promethium are radioactive with short halflives, they do not occur naturally.98
In the original periodic table by Dmitri Mendeleev, there were 62 known elements listed. What set Mendeleev's table apart from others around the same time is that he allowed gaps for elements that completed trends, and also included some elements that had not been completely confirmed at the time. At current, there are 118 elements in the periodic table, 6 of which have not yet been given an IUPAC name. All of the elements from Americium onwards are artificial, and not found anywhere in nature. Some other radioactive elements are present in nature, usually as decay products from higher radioactive elements.
Sulfur is one of the 92 naturally occurring elements, and is not a compound of any others. So you can't split or decompose sulfur to get any other elements, and you can't combine other elements to make sulfur.
In the last years technetium, prometium, neptunium and plutonium was found in the nature but in extremely low concentrations.Because they are found in the universe. They have been observed in the spectrum of certain stars.
