What else can I help you with?
What elements before neptunium are not found in nature?
All the elements before neptunium are found in the nature. Also neptunium can be found in the nature only in ultratraces resulting from nuclear weapons experiments or other experiments.
Are all known elements found in nature?
no there are nuclear atom
What elements can be found in nature?
All the elements with the atomic number in the range 1-97.
Can new elements be found in the nature?
There aren't any more "new" elements that can be found in nature. The only elements left to discover are all man-made "super-heavy elements" (The uuu, uub, uut, etc. in the periodic table).
Is all the elements on the periodic table found in nature?
Absolutely not. The vast majority are found in a combined state in nature. Iron is not found as metal but always as an ore of mixed oxides etc. The halogens and all group 1,2,3 metals are always found combined etc.
Where were thee elements that are found in nature found?
i thought all elements are found in nature, only some need to be specifically extracted to become lone, and not bonded with other elements. there are very few atoms that are found lone and singular, and most need man-made machinery to extract it.
How many elements have been found to occur in nature?
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 elements occur in nature?
Elements that occur naturally in nature include hydrogen, helium, oxygen, carbon, nitrogen, and others. These elements make up the building blocks of all matter in the universe and are found in various compounds and substances on Earth and beyond.
What elements are found as elements?
well some of the nature elements are known as Fire, Water, Earth, and Air Another answer I think what you may mean is what elements (chemical elements - not those in the answer above) are found in an uncombined form in nature. Well, not many. Gold is one. Nitrogen gas, oxygen, all the inert gases are others
What two elements are never found as elements in nature because they combine so easily with other substances?
Fluorine and francium are two elements that are never found as elements in nature due to their high reactivity. Fluorine readily reacts with almost all elements, while francium is extremely radioactive and decays quickly into other elements.
Why does the periodic table include elements that arent found naturally?
Because it is intended to represent all known elements, not only those which exist in nature.
Is actinide considered a synthetic element?
Actinide is not an element, but is a series of elements. Of the actinide series of elements, all except actinium, thorium, protactinium, and uranium are considered to be synthetic elements because they are not found in nature in appreciable amounts.
