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.
What else can I help you with?
Where are elements 112-118 found?
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.
Do all the 116 known elements occur naturally on Earth?
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.
Why silver gold and platinum occurs freely in nature?
Silver, gold, and platinum occur freely in nature because they are relatively unreactive elements that do not easily combine with other elements. This allows them to exist in their elemental form in areas where they have been deposited through various geological processes.
How many elements have been found currently?
Over 118 elements have been discovered and confirmed on the periodic table.
How many naturally occurring elements are found on this planet?
I say there are 92. At school, we were taught that there are 92 naturally occurring chemical elements on Earth. They are all the elements from hydrogen to uranium. However it's a bit more complicated than that. Here's some more detail: There are 2 elements of the first 92 that are so unstable they are not found in nature. Actually minute traces of these have now been detected, I believe. There are 2 elements beyond uranium that do occur naturally as the product of the radioactive decay of Uranium. So, the final total is probably 92. However, it may be anything from 90 to 94, depending on what you include.
How many elements are on the periodic table that do not occur in nature on earth?
There are variety of such elements. They have not been found on earth's surface.
How many elements have been found to occur in?
92
How many approximately elements in nature?
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.
When was the first homosexual case found?
Homosexuality doesn't occur in "cases." It's part of human nature, and has been around as along as humans have been around.
Where are elements 112-118 found?
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.
Why are technetium neptunium and promethium considered natural elements even though they are not found on earth?
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.
Do all the 116 known elements occur naturally on Earth?
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.
What elements on the periodic table occur naturally?
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.
Why silver gold and platinum occurs freely in nature?
Silver, gold, and platinum occur freely in nature because they are relatively unreactive elements that do not easily combine with other elements. This allows them to exist in their elemental form in areas where they have been deposited through various geological processes.
The heaviest element found in nature is?
I believe it is Uranium. All elements heavier than uranium are man-made. Here's an interesting article... http://space.newscientist.com/article/dn13828-has-the-heaviest-element-been-found.html
How many known elements were published on the periodic table?
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.
What can elements make?
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.
