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

Synthetic elements are elements that do not naturally occur on Earth and must be created in a laboratory through nuclear reactions. They are typically unstable and have short half-lives. Some examples of synthetic elements include americium, einsteinium, and oganesson.
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.
Man-made elements are created by humans through nuclear reactions, while synthetic elements are created in a laboratory by combining natural elements. The presence of man-made elements on Earth is a result of nuclear testing or accidents. Synthetic elements are not found naturally on Earth and must be produced in a controlled environment.
Elements that are made in a laboratory are typically referred to as synthetic elements. These elements are not found naturally on Earth and are produced by scientists through various experimental methods. Examples of synthetic elements include einsteinium and seaborgium.
Synthetic elements can be harmful due to their radioactive properties, which can cause damage to cells and DNA, leading to serious health problems like cancer. Additionally, they may have unknown toxicological effects on the environment and ecosystems. Improper handling and disposal of synthetic elements can also lead to contamination of air, water, and soil.
All the synthetic elements on the Periodic Table appear after Uranium (atomic no. 92). These are the only synthetic elements.
Yes, all synthetic elements are man made.
Synthetic or man-made elements. Obviously synthetic sounds significantly cooler.

Elements that cannot be found on Earth naturally but can be created artificially are called synthetic elements. These elements are typically produced in laboratories through nuclear reactions or particle accelerators. Examples of synthetic elements include technetium and americium.
Yes, they are true chemical elements but man made.
Synthetic elements are obtained by nuclear reactions.
Creation of synthetic elements in the laboratory is not based on nuclear fusion.
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.
