Is beryllium like scandium?

Just want to know.

Beryllium is better than scandium in my opinion, but its very toxic.

Description

Here is a brief description of beryllium.

* Standard state: solid at 298 K
* Colour: lead grey
* Classification: Metallic
* Availability: beryllium is available in several forms including foil, lump, and powder. Small and large samples of beryllium foil can be purchased from Advent Research Materials
via their web catalogue.

Beryllium is a Group 2 (IIA) element. At ordinary temperatures, beryllium resists oxidation in air. Its ability to scratch glass is probably due to the formation of a thin layer of the oxide. Aquamarine and emerald are precious forms of the mineral beryl, [Be3Al2(SiO3)6].

Isolation
Here is a brief summary of the isolation of beryllium.

Beryllium metal is available commercially and so would never normally be made in the laboratory. Its extraction from ores is complex. The mineral beryl, [Be3Al2(SiO3)6] is the most important source of beryllium. It is roasted with sodimu hexafluorosilicate, Na2SiF6, at 700°C to form beryllium fluoride. This is water soluble and the beryllium may be precipitated as the hydroxide Be(OH)2 by adjustment of the pH to 12.

Pure beryllium may be obtained by electrolysis of molten BeCl2 containing some NaCl. The salt is added since the molten BeCl2 conducts very poorly. Another method involves the reduction of beryllium fluoride with magnesium at 1300°C.

Here is a brief description of beryllium.

* Standard state: solid at 298 K

For those of you who dont know 298K is 25degrees celcius. That means that beryllium will not be completly solid at room temperature (21degrees celcius or 294K) So its probably not really suitable for armour at all.

Thanks Ill use scandium then (for vapourbots for now)

Info from http://www.matweb.comwww.matweb.com

Melting point 1273 - 1283 °C 2320 - 2340 °F

I would say, it will be solid in every possible RW application.

Beryllium

Sorry Mario is correct. They are obviously taking 298K as room temperature (25degrees celcius). Also when you think about it if its solid at 25degrees then it will obviosuly still be a solid at 21degrees as I am unaware of anything that changes from a solid to a liquid by cooling.

My appoligies for the mistake

Ian, Helium 3 will change from a liquid to a solid under certain conditions, it has to be at 30 atmospheres and 0.5 kelvin towards absolute zero.

And if we have event on the planet Jupiter well let you know. Trouble will be finding a nearby Travelodge

Karoline travel lodges are everywhere. Im sure theres one in that area!

Oh come on! Even if there is one there, it will be full up by now

Bloody Martians! They grab all the loungers by the methane pool and sling their slimy green towels over em. GGGGGRRRRR!

More like the Martians have their own robot arena with robot parts strewn everywhere.
