Alkaline Earth Metals

Beryllium has more covalent nature due to its smallest size, Highest ionization energy, high electropositive nature and strongest polarizing nature. Because of these, Beryllium differs from other alkaline earth metal properties. It is the hardest metal among alkaline earth metals; Does not react with water even at red hot conditions.

Alkaline Extraction

Apr 12, 2021Alkaline Lysis Alkaline lysis is the method of choice for isolating circular plasmid DNA, or even RNA, from bacterial cells. It is probably one of the most generally useful techniques because it is a fast, reliable and relatively clean way to obtain DNA from cells. If necessary, DNA from an alkaline lysis prep can be further purified. Alkaline lysis depends on a unique

Properties of Copper: Chemical, Mechanical and Physical

The strength and hardness of copper can also be increased by alloying, but this results in a decrease in electrical conductivity. The strongest copper alloy of all is produced by alloying with beryllium, followed by an age hardening heat treatment resulting in a tensile strength of up to 1500 N/mm.
