How many elements are there in nature?
Of these 118 elements, 94 occur naturally on Earth. Six of these occur in extreme trace quantities: technetium, atomic number 43; promethium, number 61; astatine, number 85; francium, number 87; neptunium, number 93; and plutonium, number 94.
What are the top 5 most common elements?
1.) Hydrogen. Created during the hot Big Bang but depleted by stellar fusion, ~70% of the Universe remains hydrogen.
How are elements found in nature?
The elements found in nature are elements with atomic numbers 1 (hydrogen) through 98 (californium). The rare elements are produced by radioactive decay and other nuclear processes of more common elements. For example, francium is found in pitchblende as the result of alpha decay of actinium.
