Elements past 92 are considered transuranium elements, which are all synthetic and are created artificially in laboratories. These elements do not occur naturally on Earth.
There are 118 known chemical elements in the periodic table, with the most recent element being Oganesson.
The group of elements with only 5 elements are the halogens in group 17 of the periodic table. These elements are fluorine, chlorine, bromine, iodine, and astatine.
Elements beyond uranium are known as transuranium elements, which are all synthetic and unstable. They are typically produced in laboratories through nuclear reactions and have very short half-lives. These elements are important for scientific research into nuclear structure and properties.
Artificial grass is typically made from synthetic materials such as polyethylene or polypropylene. These materials are designed to mimic the look and feel of natural grass while being durable enough to withstand outdoor elements. Artificial grass also often includes a backing material for support and stability.

94 non-artificial, 24 artificial and 118 in all (2012 data)
None - they are all radioactive.
there are 24 is what derek barker has been told
Artificial Elements can only be made by synthesisation in a lab (by firing an atom at a projectile). Wheras natural elements can be found naturally.
Today are known 118 chemical elements; 98 are considered as natural elements (but some have also and an artificial origin).
Mendelevium is an artificial, radioactive element, actinides group. Md don't contain another elements !
94 natural elements and 14 artificial elements
Artificial elements.
In particle accelerators.

"Artificial transmutation" is a nuclear reaction induced in laboratory, its man made. Artificial radioactivity is a radioactive disintegration phenomenon supported by artificial isotopes.
