Question

How many elements are present not in nature
​

Answer 1

Explanation:

Some elements have been made by man, but do not exist naturally. Have you ever wondered how many elements are found in nature? Of the 118 elements that have been discovered, there are 90 elements that occur in nature in appreciable amounts.

Answer 2

Answer:

Elements 43 (Technetium) and 61 (Promethium) do not occur naturally, so that would make for only 90 naturally occurring elements. Element 83 (Bismuth) is the heaviest element which has any stable isotopes. All elements with more than 83 protons i.e. Element 84 (Polonium) and beyond have only unstable isotopes.
