As a domain expert in the field of chemistry, I often delve into the intricacies of elements and their properties. The periodic table, a systematic representation of all known elements, is a cornerstone of my studies. It's a fascinating subject that encompasses the very building blocks of the universe. When it comes to the heaviest elements, the conversation can take a few different turns, depending on whether we're discussing natural or synthetic elements.
The heaviest element that occurs naturally on Earth is Uranium, with an atomic number of 92. It has several isotopes, one of which has an atomic mass of approximately 238.0289. Uranium is a significant element not only because of its natural occurrence but also due to its applications in nuclear power and as a material for nuclear weapons.
However, when we shift our focus to the realm of synthetic or man-made elements, the picture changes. Scientists have been able to create heavier elements in laboratories through nuclear reactions. These superheavy elements are typically unstable and have very short half-lives, which makes them difficult to study and extremely rare.
Ununoctium, with the symbol Uuo and the atomic number 118, is one such synthetic element. It was first synthesized in 1999 and has been confirmed as the heaviest element to date. However, it is important to note that the discovery of new elements is an ongoing process. As of my last update, element 118 remains the heaviest element that has been synthesized.
The creation of a new element often involves smashing lighter elements together at high speeds, a process that requires immense energy and sophisticated equipment. The International Union of Pure and Applied Chemistry (IUPAC) is responsible for validating new elements and assigning them official names and symbols.
It's also worth mentioning that the quest for superheavy elements is not just about finding the heaviest; it's also about understanding the limits of the periodic table and the properties of these exotic substances. Theoretical models predict the existence of an "island of stability" for superheavy elements, where elements with specific numbers of protons and neutrons might exhibit longer half-lives and be more stable than their neighbors.
In conclusion, while Uranium is the heaviest naturally occurring element, the title for the heaviest element overall goes to Ununoctium, which is a synthetic creation. The field of chemistry is always evolving, and with ongoing research, we may one day discover or create even heavier elements that could redefine our understanding of the periodic table.

When a heavier element is discovered (e.g., element 120), then that will become the new heaviest element. Ununoctium is the heaviest element, but it is man-made. The heaviest naturally-occurring element is Uranium (atomic number 92, atomic weight 238.0289).
