Discoverer: Scientists at Dubna, Russia (1964)/Albert Ghiorso et. Americium is a transuranic member of the actinide series, in the periodic table located under the lanthanide element europium, and thus by analogy was named after the Americas. Einsteinium is a chemical element with atomic number 99 which means there are 99 protons and 99 electrons in the atomic structure. Commercially, thallium is produced as a byproduct from refining of heavy metal sulfide ores. Because of its closed-shell electron configuration, its density and melting and boiling points differ significantly from those of most other lanthanides.

Gold is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. The chemical symbol for Astatine is At. Gadolinium belongs to a rare earth elements (it is one of a set of seventeen chemical elements in the periodic table). Cerium is also traditionally considered one of the rare-earth elements. Uranium has the highest atomic weight of the primordially occurring elements. Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). Mendelevium is a metallic radioactive transuranic element in the actinide series, it is the first element that currently cannot be produced in macroscopic quantities. Caesium is a soft, silvery-gold alkali metal with a melting point of 28.5 °C, which makes it one of only five elemental metals that are liquid at or near room temperature.
