Verified step by step guidance1
Understand that the question asks for the number of elements currently recognized on the modern periodic table, which is a factual piece of information rather than a calculation.
Recall that the modern periodic table includes all elements that have been discovered and officially recognized by IUPAC (International Union of Pure and Applied Chemistry).
Note that the periodic table is arranged by increasing atomic number, and the highest atomic number element officially recognized sets the total count of elements.
Remember that as of the latest updates, the highest atomic number element officially recognized is element 118, known as Oganesson (Og).
Therefore, the total number of elements currently recognized on the modern periodic table is 118.
