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. Except for francium, they were all discovered through synthesis before being found in nature.Element nameChemical

∙ 12y agoAny element with atomic number 95 (Americium [Am]) or upwards is synthetic. A synthetic element is an element that was never or is no longer naturally occuring. All the currently synthesised elements are radioactive, but not all radioactive elements are synthesised.

∙ 12y agoA synthetic (or artificial) element is an element that is synthesised in a lab and is not naturally occuring. The synthetic elements start at Neptunium (Np) any are all synthetic from then on. The synthetic element with the highest atomic number currently confirmed by The IUPAC is Ununhexium (Uuh) which is still under it's IUPAC systematic placeholder name.

∙ 7y agoSynthetic elements are those which are not found in nature and can only be produced by artificial bombardment of atoms of other elements by sub-atomic particles.

How are synthetic elements useful?
Synthetic Elements are used in smoke detectors.
How might synthetic elements be harmful?
Synthetic elements might be harmful if they are ingested or inhaled. The elements can cause damage to the lungs, brains, and heart.
Why are synthetic elements dangerous?
While there are some stable synthetic elements (eg technetium) and also naturally occurring elements which are radioactively unstable (eg radium), synthetic elements are more likely to be radioactively unstable. Their decay process produces radioactive emissions which are hazardous.
What is the difference between an element and a native element?
Elements can either be synthetic or natural. Synthetic elements are made artificially in laboratories, while natural elements exist in their natural state in nature. Natural elements can further be defined as native elements. These elements exist in their uncombined state.
How reactive are the synthetic elements?
they are very reactive, because when the elements are spread go to facebook . com
How are synthetic elements useful?
Synthetic Elements are used in smoke detectors.
Do all synthetic elements have more than 92 elements?
All the synthetic elements on the Periodic Table appear after Uranium (atomic no. 92). These are the only synthetic elements.
Synthetic elements are formed by experimentation?
Yes, all synthetic elements are man made.
How might synthetic elements be harmful?
Synthetic elements might be harmful if they are ingested or inhaled. The elements can cause damage to the lungs, brains, and heart.
What are elements called that are created by main in a laboratory?
Synthetic or man-made elements. Obviously synthetic sounds significantly cooler.
What is synthetic elements reactivity?
not reactive
All synthetic elements are?
radioactive
What elements are radioactive and synthetic?
einsteinium,......
What are all synthetic elements?
Radioactive
What are the elements in a synthetic diamond?
Carbon
Why are synthetic elements dangerous?
While there are some stable synthetic elements (eg technetium) and also naturally occurring elements which are radioactively unstable (eg radium), synthetic elements are more likely to be radioactively unstable. Their decay process produces radioactive emissions which are hazardous.
Which element is radioactive and synthetic?
All transuranic elements are synthetic and radioactive.
