Understand that the periodic table is a chart that organizes all known chemical elements based on their atomic number, electron configurations, and recurring chemical properties.
Recognize that the number of elements on the periodic table corresponds to the number of unique atomic numbers discovered or synthesized.
Recall that the current periodic table includes all elements from atomic number 1 (Hydrogen) up to the highest confirmed element.
Note that the highest confirmed element as of now has the atomic number 118, which means there are 118 elements represented on the periodic table.
Therefore, the total number of elements currently represented on the periodic table is 118.
