Flerovium is radioactive and has the symbol Fl and the atomic number 114. The element is named after Russian physicist Georgy Flyorov, who founded the Joint Institute for Nuclear Research in Dubna, Russia, where the element was first discovered in 1999.
This list contains the 118 elements of chemistry. For chemistry students and teachers: The tabular chart on the right is arranged by Atomic number. The first chemical element is Hydrogen and the last is Ununoctium.
Livermorium is a synthetic element with the symbol Lv and an atomic number of 116. It was first reported by Russian scientists from Dubna (Joint Institute for Nuclear Research) in 2000. Its former name was ununhexium and the name Livermorium name was adopted by IUPAC on May 31, 2012.
Because electrons have non zero rest mass, they cannot exceed the vacuum speed of light according to Einstein's theory of relativity. Thus, atoms with Z > 137 cannot exist.
Einsteinium - Element information, properties and uses | Periodic Table.
No unbinilium atoms were identified. Neither element 119 nor element 120 was observed.
Despite several reported observations, more recent studies suggest that these experiments were insufficiently sensitive; hence, no unbihexium has been found naturally or artificially.
Since element 123 is unknown, it has no biological role.
Astatine (At) may be the rarest naturally occurring element in the Earth's crust, but it is a member of the halogen family [fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At)] and is presumed to have characteristics similar to other Group 17 elements.
Ununennium, or element 119, is a predicted chemical element. Its symbol is Uue. Ununennium and Uue are substitute names made by the IUPAC, (meaning "one-one-nine-ium" in Latin) until permanent names are made. Ununennium is the element with the smallest atomic number that has not been created yet.
There are only two chemical elements whose name begins with the letter Z. These elements are zinc and zirconium, both of which are classified as transition... See full answer below.
This is a list of the 118 chemical elements that have been identified as of 2023.
Unbiunium, also known as eka-actinium or simply element 121, is the hypothetical chemical element with symbol Ubu and atomic number 121. Unbiunium and Ubu are the temporary systematic IUPAC name and symbol respectively, which are used until the element is discovered, confirmed, and a permanent name is decided upon.
Unbiseptium, Ubs, is the temporary name for element 127.
Tennessine is a synthetic chemical element with the symbol Ts and atomic number 117. It is the second-heaviest known element and the penultimate element of the 7th period of the periodic table.
The element which comes on 128 number is Trititanium (Tt).

roentgenium (Rg), artificially produced transuranium element of atomic number 111. In 1994 scientists at the Institute for Heavy Ion Research (Gesellschaft für Schwerionenforschung [GSI]) in Darmstadt, Ger., formed atoms of element 111 when atoms of bismuth-209 were bombarded with atoms of nickel-62.
The first report of the discovery of element 105 came from the Joint Institute for Nuclear Research (JINR) in Dubna, Moscow Oblast, Soviet Union, in April 1968.
Oganesson has the highest atomic number and highest atomic mass of all known elements.
Although there are elements we have not yet created or found in nature, scientists already know what they will be and can predict their properties. For example, element 125 has not been observed, but when it is, it will appear in a new row of the periodic table as a transition metal.
Schrodium is the provisional non-systematic name of a theoretical element with the symbol So and atomic number 150. Schrodium was named in honor of Erwin Schrödinger (1887–1961), who developed his equation for quantum mechanics.
Nihonium was discovered on August 12, 2012 by Kosuke Morita's RIKEN collaborative team in Japan. It was the first chemical element ever discovered in Asia. The discovery was formally accepted on December 30, 2015 by IUPAC and IUPAP, and a new superheavy element took its place in the seventh row of the periodic table.
