Synthetic elements are unstable chemical elements not naturally found on the earth. They are synthesized in the laboratory. All of them are unstable and radioactive in nature, which means they emit radiations and decay into other elements.
A synthesised element is any element that isn't naturally occuring and can only be produced by synthesisation. The synthesised elements are on the Periodic Table from element Americium (atomic no. 95) onwards. Most of the synthesised elements are part of the transition metals.
Californium (Cf) is named after California, the American State. This is because the element was synthesized at the University of California, Berkeley.
The chemical symbol Rg stands for Roentgenium, which is a synthetic element with atomic number 111. It is a highly unstable and radioactive element that was first synthesized in 1994.
The element dubnium is not mined. This metal is what is called a transactinide element, and it is not found anywhere in nature. All of the dubnium on earth has been synthesized in high energy physics laboratories. Additionally, all of it is unstable, and it is, therefore, radioactive. Use the link below to learn more about this element.
Dimedone is synthesized from mesityl oxide and diethyl malonate .

Neon is an element, therefore it is not synthesized, it is just extracted from the air by a process of fractional distillation.

NOTHING!
Yes nickel is a natural element not synthesized in a nuclear reactor or similar.
Every element after 92 which is uranium
seaborgium:a synthetic transuranic element,synthesized and made in 1974
Dubnium is a man made chemical element.
This element is lawrencium.
you don't need to synthesize it because it is an element.. Cl.. all you have to do is harvest it.
astatine, element 85
I don't know WHY, per say, but I know it would be metal. toodles.
noble halogens
