beryllium

/be·ryl·li·um/ (Be) (bah-ril´le-um) a chemical element, at. no. 4.

beryllium (Be)

a steel-gray, lightweight metallic element. Its atomic number is 4; its atomic mass is 9.012. Beryllium occurs naturally as beryl and is used in metallic alloys and in fluorescent powders. Inhalation of beryllium fumes or particles may cause the formation of granulomas in the lungs, skin, and subcutaneous tissues. See also berylliosis.

ber·yl·li·um

(Be) (bĕr-ilē-ŭm)
A toxic white metal element belonging to the alkaline earths; atomic no. 4, atomic wt. 9.012182; widely used in dentistry as a hardening agent in alloys.

Beryllium

A steel-grey, metallic mineral used in the aerospace and nuclear industries and in a variety of manufacturing processes.
Mentioned in: Berylliosis

ber·yl·li·um

(bĕr-ilē-ŭm)
A white metal element belonging to the alkaline earths; a component of some alloys used in dentistry.

beryllium (Be) (bəril´ēəm),

n a steel-gray, lightweight metallic element with an atomic number of 4 and an atomic weight of 9.01218. Alloys are used in fluorescent powders. Inhalation of beryllium fumes or particles may cause the formation of granulomas in the lungs, skin, and subcutaneous tissues.
