bo·ron

 (bôr′ŏn′)
n. Symbol B
A nonmetallic element that is amorphous and brown or crystalline and black, and is extracted chiefly from kernite and borax and used in flares, propellant mixtures, nuclear reactor control elements, abrasives, and hard metallic alloys. Atomic number 5; atomic weight 10.811; melting point 2,075°C; boiling point 4000°C; specific gravity (crystal) 2.34, (amorphous) 2.37; valence 3. See Periodic Table.


bo·ron′ic (bə-rŏn′ĭk, bô-) adj.

boron

(ˈbɔːrɒn)
n
(Elements & Compounds) a very hard almost colourless crystalline metalloid element that in impure form exists as a brown amorphous powder. It occurs principally in borax and is used in hardening steel. The naturally occurring isotope boron-10 is used in nuclear control rods and neutron detection instruments. Symbol: B; atomic no: 5; atomic wt: 10.81; valency: 3; relative density: 2.34 (crystalline), 2.37 (amorphous); melting pt: 2092°C; boiling pt: 4002°C
[C19: from bor(ax) + (carb)on]

bo•ron

(ˈbɔr ɒn, ˈboʊr-)

n.
a nonmetallic element occurring naturally only in combination, as in borax or boric acid: used in alloys and nuclear reactors. Symbol: B; at. wt.: 10.811; at. no.: 5.
[1805–15; bor (ax1) + (carb) on]
bo•ron•ic (ˌb ɔˈrɒn ɪk, boʊ-) adj.

bo·ron

(bôr′ŏn′)
Symbol B A shiny, brittle, black nonmetallic element extracted chiefly from borax. It conducts electricity well at high temperatures but poorly at low temperatures. Boron is necessary for the growth of land plants and is used to make soaps, abrasives, and hard alloys. Atomic number 5. See Periodic Table.
