Glucinum \Glu*ci"num\, n. [Cf. F. glucinium, glycium, fr. Gr. ?,
sweet. Cf. Glycerin.] (Chem.)
A rare metallic element, of a silver white color, and low
specific gravity (2.1), resembling magnesium. It never occurs
naturally in the free state, but is always combined, usually
with silica or alumina, or both; as in the minerals
phenacite, chrysoberyl, beryl or emerald, euclase, and
danalite. It was named from its oxide glucina, which was
known long before the element was isolated. Symbol Gl. Atomic
weight 9.1. Called also beryllium. [Formerly written also
glucinium.]

Beryllium : Beryllium: A toxic metal found in ores containing other elements that is used in making metal alloys for nuclear reactors and the aerospace industry. Acute exposure to beryllium fumes can
cause a severe, sometimes fatal pneumonitis (inflammation of the lungs). Chronic overexposure to beryllium is more common and causes a diffuse inflammatory reaction in the lungs resulting in granulomas
and fibrosis of the lungs and, in time, increasing shortness of breath. Beryllium poisoning is termed berylliosis.
