The atomic weight of rubidium is 85.4678 amu. The two naturally occurring isotopes of rubidium have the following masses. a) ^(85)Rb, 84.9118 amu b) ^(87)Rb, 86.9092 amu Calculate the percent of each isotope in naturally occurring...
ofimust be high: it may well be 9/2, or perhaps higher; in order to find the exact value, experiments are being made to determine very accurately the intensity ratio of the components.I have also examined the structure of the lines Ifli - 3 2Pi and S卤 - 3 *P$ of rubidium. Thes...

Beneficial reuse of brine could also be the key to solving the energy sustainability challenges of desalination. A type of next generation nuclear power plant will use thorium and rubidium as a power source instead of uranium. Very small plants with capacity of between 10 and 50 MW could power...
Sample Group: Atomic Emission Lamps Aluminum-scandium master alloy. This irregular lump comes from Tim Worstall, the world's leading expert on the scandium trade by virtue of the fact that he is a good fraction of the world's scandium traders. Virtually no pure scandium metal is sold in th...

ATOMIC WEIGHTS OF THE ELEMENTS 1983Abstract —Thebiennial review of atomic weight, &(E), determinationsand other cognate data have resulted in the following changes inrecommended values (1981 values in parentheses): Helium 4.002602 ± 2(4.00260 ± 1); Lithium 6.941 ± 2 (6.941 ± 3); Boron ...
These elements were given footnote “r” in the IUPAC Table of Standard Atomic Weights to indicate that a range in isotopic composition of normal material prevents a more precise standard-atomic-weight value from being given. Until the publication of the 2009 Table of Standard Atomic Weights, ...
Rubidium has an atomic radius of 2.48 Å; the ionic radius of Rb+ is 1.49 Å. The element has a density of 1.525 g/cm3 (0°C), a melting point of 38.9°C, a boiling point of 703°C, a specific heat of 335.2 joules/kg/°K (0.08 calorie/g/°C) and a coefficient of ...
