Natural ytterbium is composed of seven stable isotopes: 168 Yb, 170 Yb, 171 Yb, 172 Yb, 173 Yb, 174 Yb, and 176 Yb, with 174 Yb being the most common, at 31.8% of the natural abundance). Thirty-two radioisotopes have been observed, with the most stable ones being 169 Yb with a half-life of 32.0 days, 175 Yb with a half-life of 4.18 days, and ...
Yb + 3 N 2 O 4 → Yb(NO 3) 3 + 3 H 2 O. Ytterbium phosphide is the phosphide of ytterbium in the +3 oxidation state. [13] [14] [15] It can be obtained by reacting ytterbium and phosphine in liquid ammonia to form Yb(PH 2) 2 ·5NH 3, which can be decomposed to obtain ytterbium phosphide: [16] Yb(PH 2) 2 •5NH 3 → Yb(PH 2) 2 + 5NH 3 2Yb(PH 2 ...
Naturally occurring ytterbium (70 Yb) is composed of seven stable isotopes: [n 1] 168 Yb, 170 Yb– 174 Yb, and 176 Yb, with 174 Yb being the most abundant (31.83% natural abundance). 30 radioisotopes have been characterized, with the most stable being 169 Yb with a half-life of 32.014 days, 175 Yb with a half-life of 4.185 days, and 166 Yb with a half-life of 56.7 hours.

YB won the leg in the Nep Stadium 2–1. 26 November 1958 saw the European premiere in Wankdorf; 28,000 spectators celebrated the Young Boys' 4–1 victory. In the second round, YB met the East German champions SC Wismut Chemnitz and the Wankdorf was filled with 32,000 spectators. The teams drew 2–2 after a 2–0 lead for the Young Boys.
Ytterbium(III) oxide is the chemical compound with the formula Yb 2 O 3. It is one of the more commonly encountered compounds of ytterbium. It occurs naturally in trace amounts in the mineral gadolinite. It was first isolated from this in 1878 by Jean Charles Galissard de Marignac. [3]
YB 66 was discovered in 1960 [17] and its structure was solved in 1969. [16] The structure is face-centered cubic, with space group Fm 3 c (No. 226), Pearson symbol cF1936 and lattice constant a = 2.3440(6) nm. There are 13 boron sites B1–B13 and one yttrium site. The B1 sites form one B 12 icosahedron and the
