Several elements aren't found in their elemental form in nature: mostly alkali metals and alkali earth metals. Synthetically produced elements (with atomic numbers upward from 93) are also not found in nature.

∙ 13y agoI don't think that there is a universal name for them, at least not to IUPAC standards, but the convention in chemistry is to refer to them as "synthetic elements".
There are isotopes of some elements that are not normally found in nature but result from the radioactive decay of other, more massive elements. These can be called "from decay" isotopes.

Many elements found in nature exist as?
The chemical substances found in the atmosphere exist as gases.
How many elements cant be found in nature?
Uranium, element number 92, is the largest naturally occurring element. However, francium, 87, and astatine, 85, along with any element with an atomic number larger than 92 are not found in nature. They are produced in the laboratory. If they do occur naturally they are in exceedingly small quantities. So to answer your question "How many elements can't be found in nature?" about 16 or a few more.
How many elements are found in nature as a liquid?
Bromine and Mercury. However, they are not found in the elemental state but in compounds. In addition Gallium, Francium and Cesium are extremely cose to being liquid in their elemental form at normal temperatures and pressures.
How Many Radioactive Elements Are Made in the Laboratory?
About 28 elements were discovered in the laboratory. But after the man made preparation some elements were discovered also in nature in very extremely traces: Pm, Tc, Pu, Np, Am, Cm, Bk.
How many elements are there in total?
117 know ones (some are yet to be discovered)
What are elements called when they are found in nature?
Elements found in nature are referred to natural elements, as opposed to synthetic, which are man made.
What form are most elements in nature?
Most elements in nature are found in the solid state.
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.
What are elements that can not be found on earth and can be created called?
Synthetic elements are not found in nature but are created in laboratories.
Are alkali metals always found pure in nature?
Alkali metals are not found as pure elements in nature.
How are usually found?
In the nature the majority of chemical elements are found as compounds.
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.
Which two groups of elements are never found uncombined in nature?
group 1 elements
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).
Are all known elements found in nature?
no there are nuclear atom
How do most elements in nature exist?
Most elements found in nature are in the combined form because of the ionic and hydroqen bondinq.
