Partial credit for 92 natural elements on Earth. The way people find that answer is counting all the elements on the periodic table from hydrogen (1) to uranium (92) on the theory that uranium is the cut-off point for naturally occurring elements.
- The problem is that scientists have found really small amounts of elements 93-98 in ores of uranium on Earth along with tiny amounts of technetium (43) bringing us to a total of 98 elements on Earth.
No credit for 18 elements in the human body. Scientist are arguing about the usefulness certain elements like strontium, but 28 or 29 seems to be a very safe number.
