As of the latest update, there are 118 elements on the periodic table. These elements are organized based on their atomic number, electron configurations, and recurring chemical properties.
The periodic table is divided into groups and periods. Groups are the vertical columns, and periods are the horizontal rows. Each element is represented by its chemical symbol, such as H for Hydrogen, O for Oxygen, and so on.
The first 94 elements occur naturally, while elements 95 to 118 have been synthesized in laboratories or nuclear reactors. Scientists continue to research and discover new elements, which may lead to updates in the periodic table in the future.
