How many known elements are there currently?

The current known number of elements is 118. This total includes the elements that are found naturally as well as those that have been synthesized in laboratories. Elements are defined by the number of protons in their atomic structure, and the periodic table has been updated over the years as new elements have been discovered or created through nuclear reactions.

The periodic table is organized in such a way that it reflects not only the number of protons but also the properties of the elements, allowing for a comprehensive understanding of chemical behavior. Elements 1 through 92 occur naturally on Earth while elements beyond 92 (known as transuranium elements) have been synthesized.

Science continues to explore possibilities of discovering even more elements, but as of now, the total stands firmly at 118 known elements. This total includes the recently confirmed heavy elements like copernicium and oganesson.
