In my high school lessons, it's always been said "Among 92 naturally occurring elements...", "Only 92 elements can be found in nature", ...
Although this fact seemed to be reliable, there was still one little nagging doubt at the back of my mind. So I searched for the exact number in the internet but found a lot of different numbers; from 88 to 98!
Now my questions are: (Quotes are regular Doubtful answers.)
What exactly is a naturally occurring element?
An element that has at least one isotope that occurs naturally on "Earth".
How many naturally occurring elements has been observed? -the Latest Version!An element that has at least one isotope that can be found in "Nature".
Would you please tell me the exact atomic no range of such elements (with exceptions)?88, 90, 92, 93, 94, 98
I would be really grateful if anyone could answer my questions. (Based on Information from the Latest Observations & Reliable Sources)From atomic no 1 to 92 -written in our books!
