Ytterbium is a chemical element in the periodic table that has the symbol Yb and atomic number 70. A soft silvery metallic element, ytterbium is a rare earth of the lanthanide series and is found in the minerals gadolinite, monazite, and xenotime. The element is sometimes associated with yttrium or other related elements and is used in certain steels. Natural ytterbium is a mix of seven stable isotopes. Ytterbium - Notable characteristics.

It is the 20th prime number. The next is 73, with which it composes a twin prime. It is also a permutable prime with 17. If we add up the primes less than 71 (2 through 67), we get 568, which is divisible by 71, 8 times. 71 is the largest supersingular prime. Also, 712 = 7! + 1, making it part of the last known pair of Brown numbers, as (71, 7). It is an Eisenstein prime with no imaginary part and real part of the form 3n − 1 ...

Ytterbium is a soft, malleable and rather ductile element that exhibits a bright silvery luster. A rare earth element, it is easily attacked and dissolved by mineral acids, slowly reacts with water, and oxidizes in air. Ytterbium has three allotropes which are called alpha, beta and gamma and whose transformation points are at -13 ° C and 795 °C. The beta form exists at room temperature and has a face-centered crystal structure while the high-temperat ...

Somewhere in the immediate area was the chief settlement or oppidum of the Parisii, a Celtic people who settled in the area during the 3rd century BC. However, dendrochronological study of wooden pilings beneath the lowest stratum of the Roman north-south axis date the road's construction after 4 CE, more than fifty years after the Roman pacification of the region. Roman Lutetia was founded above the flood-prone point where the Bièvre stream reaches the river Seine, centered on the slopes of the hill later dedicated to Saint Geneviev ...

The appearance of this element is unknown, however it is most likely silvery-white or gray and metallic. If sufficient amounts of lawrencium were produced, it would pose a radiation hazard. Very little is known about the chemical properties of this element but some preliminary work on a few atoms has indicated that it behaves similarly to the actinides. Element 103 is a d-block element analogous to lutetium and therefore is increasingly being placed with the other d-block elements in the transition metal chemical series, but it is still most o ...

The regular grid-plan of Roman Lutetia marked it as the city, in the Gallo-Roman sense. The city was the only sector in which, starting in the 2nd century CE, public monuments were constructed. The north-south axis was dictated by the need to cross the marshy riverbanks in the shortest possible distance; several routes converged at the bridgehead. The Roman public works were all on the north-facing slope of the hill of Ste Genevieve. The discovery of ancient paved roads, the established boundaries of the main monuments—the forum at the top ...

Naturally occurring ytterbium is composed of 7 stable isotopes, Yb-168, Yb-170, Yb-171, Yb-172, Yb-173, Yb-174, and Yb-176, with Yb-174 being the most abundant (31.8% natural abundance). 22 radioisotopes have been characterized, with the most stable being Yb-169 with a half-life of 32.026 days, Yb-175 with a half-life of 4.185 days, and Yb-166 with a half life of 56.7 hours. All of the remaining radioactive isotopes have half-lifes that are less than 2 hours, and the majority of these have half lifes that are less than 20 minutes. This element also has 6 meta states, with the most stable bein ...

Ytterbium was discovered by the Swiss chemist Jean Charles Galissard de Marignac in 1878. Marignac found a new component in the earth then known as erbia and named it ytterbia (after Ytterby, the Swedish town where he found the new erbia component). He suspected that ytterbia was a compound of a new element he called ytterbium (which was in fact the first rare earth to be discovered). In 1907, the French chemist Georges Urbain separated Marignac's ytterbia into two components, neoytterbia and lutecia. Neoytterbia would later become kn ...

The town was captured by the Roman Republic in 52 BC during the conquest of Gaul under Caesar. The Lutetians backed the revolt of Vercingetorix against the Romans under Caesar, reportedly contributing 8,000 men to Vercingetorix's army. It was garrisoned by Vercingetorix's lieutenant Camulogenus, whose army camped on the Mons Lutetius (where the Panthéon is now situated). The Romans crushed the rebels at nearby ...
