Verified step by step guidance1
Begin by understanding what is meant by 'naturally occurring elements'. These are elements that can be found in nature without being artificially synthesized.
Recall that the periodic table is a comprehensive list of all known elements, both naturally occurring and synthetic.
Identify the range of atomic numbers that correspond to naturally occurring elements. These typically range from hydrogen (atomic number 1) to uranium (atomic number 92).
Consider the fact that elements with atomic numbers higher than 92 are generally synthetic and not found naturally.
Conclude that the number of naturally occurring elements is the count of elements from atomic number 1 to 92, which totals 92.
