All the existing elements are natural the man made elements are rare and have a very short life.
112 Elements ( 92 Natural and 20 Man-made ) .
Rubber is a natural material derived from the latex of certain plants, such as the rubber tree. However, synthetic rubber is also made in a chemical process using petroleum byproducts. So, rubber can be both man-made and natural.
It is natural but there are man-made imitations.

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.
All the elements on the earth (excepting of course man made elements) are considered natural chemical elements.
Rubber is a natural material derived from the latex of certain plants, such as the rubber tree. However, synthetic rubber is also made in a chemical process using petroleum byproducts. So, rubber can be both man-made and natural.
Most of the elements in the Periodic Table of elements are metals. Also, most of them are made by nature. Elements with the atomic number of 1-91 are made by nature. Elements with the atomic number of 92-118 are man-made.
There's only 92 natural elements, but there are 28 man-made elements for a total of 120.
Yes! Out of the current 118 known elements 92 of them are natural occurring, and 26 are man made. Only 90 of the 92 natural elements are found on Earth. The other 2 natural elements are found in space.
Elements found in nature are referred to natural elements, as opposed to synthetic, which are man made.
