Synthetic elements are formed by experimentation?
Yes, all synthetic elements are man made.
All synthetic elements are?
radioactive
What are all synthetic elements?
Radioactive
Which element is radioactive and synthetic?
All transuranic elements are synthetic and radioactive.
After which number are all elements synthetic?
92
What is the name of the series which contains most of the synthetic and radioactive elements?
All of the actinides are radioactive, and almost all are synthetic.
Synthetic elements are found in what group?
The Actinoids group contain all the synthetic elements. All the elements that have an atomic weight of 95 and above do not occur naturally. They are part of the actinoid elemental group.
What group on the periodic table are synthetic elments?
Technetium (43), Promethium (61), and all the transuranic elements are synthetic.
What is synthetic element?
a synthetic element is not naturally found in the earth, they are handmade elements. OR elements that do not occur naturally and that are made in laboratories.
Is it true that transuranium elements are synthetic elements with atomic numbers greater than 92?
Yes. All elements classified after Element Atomic Number 92 (Uranium) (id est transuranium) are synthesised elements and can not be found naturally. They are also all radioactive, although this is the case for elements from elements 84 onwards.
What elements are synthetic elements?
Sythetic elements are those with half lifes to small to be found in nature, they are manmade and generally fairly unstable. The synthetic elements are: All elements with atomic numbers 1 through 98 are naturally occurring at least in trace quantities, but the following elements are usually produced through synthesis.

Are there more elements or more non-elements?
All matter is made up of various elements, and most elements are found in the form of compounds. There are far more compounds than there are elements.
