According to the description in the case the 5 metals are Beryllium, Lockalloy, Beryllium Copper, Columbium [an older name for niobium], Tantalum.This is the lockalloy sample from the set, the others are listed under their respective elements. Lockalloy is said to be 62% beryllium and 38% aluminum, and used in exotic supersonic aircraft.

Extraction equilibrium of beryllium and aluminum and …

Preliminary experiments on the extraction equilibrium of beryllium and aluminum were carried out with 0.20 M CYANEX 921 in kerosene at 25 °C for different shaking times and different aqueous solutions containing 5.0 mg/L beryllium or 8.5 mg/L Al(III) dissolved in 0.001 M sodium sulfate solutions at pHs 2.0, 5.0 and 9.0.

Valences of the Elements Chemistry Table

Here is a table of element valences. Remember that an element's electron cloud will become more stable by filling, emptying, or half-filling the shell. Also, shells don't stack neatly one on top of another, so don't always assume an element's valence is determined by the number of electrons in its outer shell.

Physics

Periodic table groups are based on outer shell electrons and how they can be shared between atoms to form chemical bonds. Spectral lines, however, are based on the transitions that electrons make within a single atom. "It makes sense that periodic table groups did not show the same patterns as sounds created from spectral lines," says Linz.

Beryllium

Beryllium is a silvery-white metal. It is relatively soft and has a low density. Uses. Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.
