Periodic table
- tabla periódica nf + adj (organización de elementos) periodic table n La científica recibirá una condecoración por conseguir agregar un nuevo elemento a la tabla periódica.
Listado de nombres de los elementos de la tabla periódica en inglés y español. La tabla siguiente muestra los nombres de los elementos químicos de la tabla periódica en inglés y español. Puedes utilizar CTRL + F para encontrar elementos específicos.
Los elementos químicos (chemical elements) en inglés y español son: Hydrogen, hidrógeno. Helium, helio. Lithium, litio. Beryllium, berilio. Boron, boro.
The periodic table is an arrangment of the chemical elements ordered by atomic number so that periodic properties of the elements (chemical periodicity) are made clear.
Interactive periodic table showing names, electrons, and oxidation states. Visualize trends, 3D orbitals, isotopes, and mix compounds. Fully descriptive writeups.

By virtue of its work in relation with the chemical elements, IUPAC can dispense a periodic table that is up-to-date. IUPAC involvement covers various aspects of the table and data that it unveils, and several reports and recommendations, some quite recent, attest of that input.
Assessing if an element has been discovered is not a simple task. While reviewing the discovery profiles of the transfermium elements in the early 90s, IUPAC and IUPAP set up to establish a series of criteria that must be satisfied for the discovery of an element to be recognized. See details in PAC 1991, Vol. 63, No. 6, pp. 879-886 (https://dx.doi...
In Nov 2018, a provisional report ON THE DISCOVERY OF NEW ELEMENTS was released by IUPAC/IUPAP. Criteria and guidelines for establishing priority of discovery of potential new elements are presented. learn more
The story behind the three-letter symbols is recounted in a feature prepared by Lars Öhrström and Norman Holden and published in Chem Int 2016, Vol. 38, No. 2, pp. 4-8; https://dx.doi.org/10.1515/ci-2016-0204
Claims for the discoveries of new elements appear time to time in the scientific literature. IUPAC, along with IUPAP, is involved in assessing these claims. In result, IUPAC technical reports are released that review each pertaining references and recognize the laboratory(ies) whose claims fulfill the agreed criteria.
A short review of the current procedures is published in a recent feature by John Corish; See CI 2016, Vol. 38, No. 2, pp. 9-11; https://dx.doi.org/10.1515/ci-2016-0205
On 8 June 2016, IUPAC released the provisional names for the latest 4 elements 113, 115, 117, and 118 see release and on 28 November 2016, IUPAC announced the approved names and symbols see release.
Here again, IUPAC has a set of guidelines that outline what sort of name an element can bear. Both the root and the ending must be consistent with the agreed recommendations. The detailed recommendations were published in 2002 and a revision published in 2016 to better accommodate element in group 17 and 18. See PAC 2002, Vol. 74, No. 5, pp. 787-79...
The question of precisely which elements should be placed in group 3 has been debated from time to time. An IUPAC project has been recently initiated to resolve the question. Will group 3 consist of Sc, Y, Lu, and Lr or, will it consist of Sc, Y, La and Ac?
