What is the heaviest element on the periodic table? The heaviest element on the periodic table is oganesson, which has the atomic number 118.

Oganesson is a synthetic element, meaning that it does not occur naturally on Earth. It was first synthesized in 2006 by a team of scientists at the Joint Institute for Nuclear Research in Dubna, Russia. Oganesson is a very unstable element, and only a few atoms of it have ever been produced.

Despite its instability, oganesson is an important element because it helps scientists to understand the properties of superheavy elements. Superheavy elements are elements that have atomic numbers greater than 104. These elements are all very unstable, and they all decay into lighter elements over time. However, studying superheavy elements can help scientists to learn more about the structure of the atom and the forces that hold it together.

The discovery of oganesson was a major breakthrough in the field of chemistry. It is the heaviest element that has ever been synthesized, and it has helped scientists to gain a better understanding of the periodic table. Oganesson is a reminder that there is still much that we do not know about the world around us, and it is a testament to the power of human curiosity.

Atomic number

The atomic number of an element is the number of protons in the nucleus of an atom of that element. The atomic number is a unique identifier for each element, and it determines the element's position on the periodic table. The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number, electron configuration, and recurring chemical properties.

The atomic number of oganesson is 118, which means that it has 118 protons in its nucleus. This makes oganesson the heaviest element on the periodic table, as no other element has more protons in its nucleus.

The atomic number of an element is a very important property, as it determines the element's chemical properties. For example, the atomic number of an element determines the number of electrons that the element has, which in turn determines the element's reactivity. The atomic number of an element also determines the element's position on the periodic table.

Atomic mass

The atomic mass of an element is the weighted average mass of all the isotopes of that element. The atomic mass is typically given in atomic mass units (amu), where one amu is defined as 1/12 of the mass of a carbon-12 atom. The atomic mass of an element is a very important property, as it can be used to calculate the mass of an atom of that element, as well as the mass of a molecule that contains that element.

The atomic mass of oganesson is [294] amu. This means that the average mass of all the isotopes of oganesson is 294 amu. Oganesson has a total of four known isotopes, with mass numbers of 294, 293, 292, and 291. The most common isotope of oganesson is ²⁹⁴Og, which has a mass number of 294 and a half-life of 0.89 milliseconds.

The atomic mass of oganesson is a very important property, as it can be used to calculate the mass of an atom of oganesson, as well as the mass of a molecule that contains oganesson. For example, the mass of an atom of ²⁹⁴Og is 294 amu. The mass of a molecule of oganesson dioxide (OgO₂) is 310 amu.

The atomic mass of oganesson is also a very important property for scientists who are studying the properties of superheavy elements. Superheavy elements are elements that have atomic numbers greater than 104. These elements are all very unstable, and they all decay into lighter elements over time. However, studying superheavy elements can help scientists to learn more about the structure of the atom and the forces that hold it together.
