Verified step by step guidance1
Understand that the periodic table is a systematic arrangement of chemical elements based on their atomic number, electron configurations, and recurring chemical properties.
Recall that the number of recognized elements corresponds to the highest atomic number of elements that have been discovered and confirmed by the scientific community.
Note that naturally occurring elements go up to uranium, which has an atomic number of 92, but many synthetic elements have been created in laboratories beyond this number.
Recognize that the current periodic table includes all elements up to element 118, which is the highest atomic number element officially recognized and named.
Therefore, the approximate number of elements currently recognized in the periodic table is 118.
