There are a number of synthetic elements. And a few that are what is called quasi-synthetic. The synthetic ones aren't found in nature. And it could be said that the quasi-synthetic ones are found in nature in only the barest trace amounts. The nice folks at Wikipedia have posted a comprehensive list, and a link is provided. That way you can scan the list quickly, and you will have the added advantage of being able to link to any element that looks interesting. Yes, that's right. All the elements on the list are actually hyperlinks to the Wikipedia article on that element. How cool is that?!
As follows. . . Technetium; Astatine; Neptunium; Plutonium; Americium; Curium; Berkelium; Californium; Einsteinium; Fermium; Mendelevium; Nobelium; Lawrencium; Rutherfordium; Dubium; Seaborgium; Bohrium; Hassium: Meitnerium. The rest, as far as A Guide To The Elements goes, are unnamed but they exist.

Element between atomic number 99 to 118 are all synthetic elements.
Namely they are: Einsteinium, Fermium, Mendelevium, Nobelium, Lawrencium, Rutherfordium, Dubnium, Seaborgium, Bohrium, Hassium, Meitnerium, Darmstadtium, Copernicium, Ununtrium, Ununquadium, Ununpentium, Ununhexium, Ununseptium and Ununoctium.
There are many elements that are synthetic, and all of them (so far!) are very radioactive.
Uranium (element 92) is the last element on the Periodic Table that seems to exist in nature. All of the elements past Uranium (elements 93 to 118) do not exist in nature, but are produced in nuclear reactors (as with, for example, Plutonium) or in particle accelerators.
The reason these elements do not exist in nature is precisely because of their radioactivity! If they were created at all in the past they would have all since decayed in to other elements.
A synthetic element is an element which is not found in nature, and is manmade.
Nobelium and Fermium are examples of synthetic elements.
Iron is a natural chemical element.
sodium
Technetium is an artificial chemical element.
Neon is a naturally-occurring chemical element, although it is not present in high concentrations in the earth's atmosphere.. Neon is an element, so it cannot be synthesized; it can only be extracted from natural sources.
The difference between naturally occuring and synthetic elements is that synthetic elements can't be found naturally - they can only be synthesised by man. Elements after no. 92 (Uranium) are all synthetic.
You can say that as long as the alpha particle itself is not originating from a radioactive element. If however one is able to isolate the helium nucleus from the elemental atom and then used for bombarding towards the beryllium then it is considered as an example of artificial radioactivity. Or the production of a radioactive element(synthetic element) like Francium can be considered artificial radioactivity.
Synthetic hair will melt. Synthetic hair is made from acrylic or plastic.
No, Bromine is not a synthetic element, it occurs naturally
Yes
it is not natural it is a synthetic element.
no
it is synthetic
No.
The first synthetic element to be made by a particle accelerator was technetium
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.
Aluminium is a natural chemical element.
Boron is a natural chemical element.
Xenon is a natural chemical element.
fermium
