Once the metal is ignited in air by heating above the oxide melting point around 2500 °C, beryllium burns brilliantly, [12] forming a mixture of beryllium oxide and beryllium nitride. Beryllium dissolves readily in non-oxidizing acids, such as HCl and diluted H 2 SO 4, but not in nitric acid or water as this forms the oxide. This behavior is ...
Even the compound beryllium fluoride, which is the most ionic beryllium compound, has a low melting point and a low electrical conductivity when melted. [ 12 ] [ 13 ] [ 14 ] All the alkaline earth metals have two electrons in their valence shell, so the energetically preferred state of achieving a filled electron shell is to lose two electrons ...
Beryl (/ ˈ b ɛr əl / BERR-əl) is a mineral composed of beryllium aluminium silicate with the chemical formula Be 3 Al 2 Si 6 O 18. [6] Well-known varieties of beryl include emerald and aquamarine. Naturally occurring hexagonal crystals of beryl can be up to several meters in size, but terminated crystals are relatively rare. Pure beryl is ...
Organoberyllium chemistry involves the synthesis and properties of organometallic compounds featuring the group 2 alkaline earth metal beryllium (Be). [2] The area remains less developed relative to the chemistry of other main-group elements , because Be compounds are toxic and few applications have been found.

BSc meteorologist Janice Davila tells Bored Panda that one of the most unknown facts from her field of expertise is that weather radars are slightly tilted upward in a half-degree (1/2°) angle.
Beryllium fluoride has distinctive optical properties. In the form of fluoroberyllate glass, it has the lowest refractive index for a solid at room temperature of 1.275. Its dispersive power is the lowest for a solid at 0.0093, and the nonlinear coefficient is also the lowest at 2 × 10 −14.
