Sistema Periodico de Los Elementos (after Antropoff)

Mario Rodríguez Peña, PhD translates the spanish text on the website:

"Periodic System of Elements, type Antropoff., 1956 Antropoff's periodic table was designed in Bonn (Germany) in 1926: It was disused after the WWII (1945) in most of the countries, except Spain. This was dated in 1956 because Mendelevium (101) was discovered and accepted by IUPAC in 1955 and in 1957, the element symbols of Argon (18), Xenon (54), Einstenium (99) and Mendelevium itself changed to the current Ar, Xe, Es and Md, respectively."
