∙ 11y agoSynthetic (artificial) elements not or no longer occurring on earth, but artificially generated by nuclear reaction.
The artificial elements include the elements technetium(atomic number Z = 43), promethium (Z = 61) and the transuraniums (Z > 92). A total of 118 elements are therefore known today. In the 70's, it could be verified that very low traces of plutonium occur in nature resulting from natural nuclear fissions (about 1 plutonium atom per 1012 uranium atoms).

What elements make up artificial flavoring?
secret.....................answer it..............
What is special about all the elements beyond uranium on the periodic table?
These elements are called transuranic elements.
Which groups of elements only have 5 elements?
Considering also very heavy artificial elements this group doesn't exist.
Elements past 92 are considered what?
Trans-uranic, man-made, artificial.
How do you list groups of elements in increasing order?
by the elements family
How do artificial elements differ from naturally occurring elements?
Artificial Elements can only be made by synthesisation in a lab (by firing an atom at a projectile). Wheras natural elements can be found naturally.
How many elements are there that are artificial?
15
How can you tell what elements exist on planet?
94 natural elements and 14 artificial elements
How are the non-natural elements of the periodic table called?
Artificial elements.
How do we make artificial elements?
In particle accelerators.
What family is plutonium is from?
Actinides group, transuranic elements, metals, artificial elements
How does artificial transmutation differ from artificial radioactivity?
"Artificial transmutation" is a nuclear reaction induced in laboratory, its man made. Artificial radioactivity is a radioactive disintegration phenomenon supported by artificial isotopes.
How many elements are their?
94 non-artificial, 24 artificial and 118 in all (2012 data)
How are the actinide series elements created?
Elements with atomic numbers 89-94: natural elements.Elements with atomic numbers 95-98: artificial elements but they are also discoverd in nature as ultratraces.Elements with atomic numbers 99-103: artificial elements.
What elements make up artificial flavoring?

What is special about all the elements beyond uranium on the periodic table?
These elements are called transuranic elements.
The term used to describe elements that are synthetic or man made?
They are called artificial chemical elements.
