What is the newest element that has been discovered?
The four newly discovered elements named
IUPAC is naming the four new elements nihonium, moscovium, tennessine, and oganesson
- Nihonium and symbol Nh, for the element 113,
- Moscovium and symbol Mc, for the element 115,
- Tennessine and symbol Ts, for the element 117, and.
- Oganesson and symbol Og, for the element 118.
- You can not create new elements by mixing different compounds. In order to create a new element you have to change the number of protons in a nucleus. It is possible to do this but it requires bombarding various elements, one with the other, by means of high energy particle accelerators.
- These different versions of hydrogen are called isotopes. All isotopes of a particular element have the same number of protons, but have a different number of neutrons. If you change the number of neutrons an atom has, you make an isotope of that element. Currently, scientists know of 118 different elements.
- The elements of the periodic table sorted by atomic number. click on any element's name for further chemical properties, environmental data or health effects. This list contains the 118 elements of chemistry. For chemistry students and teachers: The tabular chart on the right is arranged by Atomic number.

- Gold is element 79 and its symbol is Au. Though the name is Anglo Saxon, gold originated from the Latin Aurum, or shining dawn, and previously from the Greek. It's abundance in the earth's crust is 0.004 ppm. 100% of gold found naturally is isotope Au-197.
- 118 elements
The name honors Russian physicist Yuri Oganessian, a pioneer in the discovery of superheavy elements. He is the second person to have an element named after him while still alive. The first is Nobel-winning scientist Glenn Seaborg, who, among other things, discovered plutonium.
- The first successful synthesis of moscovium was by a joint team of Russian and American scientists in August 2003 at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia. Headed by Russian nuclear physicist Yuri Oganessian, the team included American scientists of the Lawrence Livermore National Laboratory.
- Element, artificial. Element not or no longer occurring on earth, but artificially generated by nuclear reaction. The artificial elements include the elements technetium (atomic number Z = 43), promethium (Z = 61) and the tran-suraniums (Z > 92). A total of 118 elements are therefore known today.
Origin of Name After Wilhelm Conrad Röntgen, who discovered X-rays Date and Place of Discovery On December 8, 1994 at the Heavy Ion Research Laboratory in Darmstadt, Germany Discovered by Team led by S. Hofmann Common Compounds There are no known compounds.
