The heaviest element known to date is oganesson.
Understanding Heavy Elements
When we talk about the "heaviest" element, we generally refer to the element with the highest atomic mass. Atomic mass is a measure of the total mass of protons and neutrons in an atom's nucleus. Elements are arranged on the periodic table in order of increasing atomic number, which is the number of protons.
Oganesson: The Current Heaviest Element
According to current scientific understanding, based on references, oganesson is the element with the highest atomic number and, consequently, the highest atomic mass. This makes it the heaviest element on the periodic table as of 2024.
- Atomic Number: 118
- Atomic Mass: Approximately 294 atomic mass units (amu)
Why Oganesson is the Heaviest
Oganesson's position at the end of the periodic table reflects its large number of protons and neutrons. It is a synthetic element, meaning it doesn't occur naturally and is created in laboratories. Because of its extreme instability, it's not something we can handle or observe easily; its existence is primarily confirmed through its decay patterns.
Key Characteristics of Oganesson
- Synthetic Element: Produced artificially in laboratories.
- Radioactive: Extremely unstable and decays very quickly.
- Superheavy: Occupies a region of the periodic table with the heaviest elements.
