The jewels Emerald and Beryl are considered by some to be of interest.
Beryllium and beryllium compounds are toxic; any applications as fertilizer !
Beryllium can form binary compounds with the majority of the nonmetals and metalloids.
Beryllium does not have any lone pairs because it forms ionic compounds where it loses its 2 outer electrons to become Be2+.
Beryllium (Be) has two valence electrons in its outer shell. To achieve a stable electron configuration, it typically forms compounds by sharing or losing these two electrons. Therefore, Beryllium does not need any additional valence electrons; it is stable with the two it has.
The element which has the same oxidation number in all of its known compounds is fluorine. Fluorine always has an oxidation number of -1 in its compounds because it is the most electronegative element.
There are many ways to make any dish interesting - think about presentation and colour.
Xenon is an element so it is not made up of any compounds.
I can't find any reference to Beryllium Sulphide - Beryllium sulfate is BeSO4
No, alkaline metal phosphates are generally insoluble.
Any reaction occur.
In order for beryllium to not be discovered, we have to presume a level of technology roughly equivalent to the 18th century (beryllium was first isolated around 1830). So, dig out your history book and look up that time period. Beryllium is used for high-tech aircraft parts, for nonmagnetic tools for radar and MRI equipment, and for some types of electronics. The chances that any of those applications could exist without a level of technology sufficient to make the existence of beryllium obvious is nil.
Anything can be interesting if you make it that. You can audition on Britain's Got Talent with any talent.
