According to the Jefferson National Linear Accelerator Laboratory, the properties of lithium are: Atomic number (number of protons in the nucleus): 3 Atomic symbol (on thePeriodic Table of Elements): Li Atomic weight (average mass of the atom): 6.941 ...
It reacts with trimethylchlorosilane to produce tris(trimethylsilyl)amine, in which the coordination number of nitrogen is 3, and the spatial configuration is a plane regular triangle. In organic synthesis or pharmaceutical synthesis, lithium bistrimethylsilylamide is usually used as a strong base to...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that ...

Lithium-ion Polymer (LiPo) battery cells with normal voltages are fully charged at 4.2V while high-voltage lithium polymer (LiHv) cells allow for a higher cut-off charging voltage at 4.35V. 4.4V, or 4.45V. What is a LiHv battery? A LiHv battery is a different type of Lithium-ion ...
Reduction of Amides Amides yield primary amines by lithium aluminum hydride reduction, whereas N-replaced and N-replaced amides produce secondary and tertiary amines, respectively. Since amides are readily prepared, their reduction is a favoured method for the making of all amine groups. ...
