How many elements are there in the periodic table currently?

• A. 92
• B. 108
• C. 118
• D. 126

Answer: (C)

The periodic table currently contains 118 elements, which encompasses all known chemical elements that have been officially recognized and named by the International Union of Pure and Applied Chemistry (IUPAC). These elements range from hydrogen, the lightest and most abundant element in the universe, to oganesson, which is one of the heaviest and most recently synthesized. Each element has a unique atomic number that corresponds to the number of protons in its nucleus and is typically organized in order of increasing atomic number in the periodic table. The count of elements may change over time as new elements are discovered or synthesized in laboratories. However, as of now, there are 118 confirmed elements. This includes not only the naturally occurring elements but also several synthetic elements that have been created through nuclear reactions. Understanding this framework is essential for studying chemistry and the properties and reactions of different substances.
