### element | metal:

Beryllium
* Most beryllium is used in the manufacture of components for the nuclear power industry.
* also dissolves in alkali solutions.
* borate with hydroxyl and fluorine.
* can also cause lung cancer
  - be electroless nickel plated, and flame or plasma sprayed
* combines with aluminium, silicon and oxygen to make a mineral called beryl.
* comes from Greek beryllos, beryl.
* deadly metal that was used in nuclear weapons production
* enters the environment principally from coal combustion.
* forms binary compounds with many non-metals.
* hard, brittle metal with a grayish-white surface.
* hard, lightweight metal that is very strong and easy to shape
  - used in the defense, auto, and electronics industries
  - with an unusually high melting point
* has four protons and four electrons
  - one of the highest melting points of the light metals
* highly efficient generator of neutrons when bombarded with alpha particles.
* hydroxide is amphoteric.
* includes atoms.
* is also present in a variety of compounds in coal, soil, and volcanic dust
  - chemical elements
  - concentrated in silicate minerals relative to sulfides
  - considered to be very toxic
  - especially toxic but extremely rare in combustible wastes
* is found in a variety of countries on five continents
  - mostly in minerals like beryl and chrysoberyl , and also salts
  - hazardous
  - high melting and light weight
  - in beryl gems such as emeralds and aquamarines
  - light, quite hard and brittle
  - more toxic in soft water than in hard water
  - non-magnetic
  - nonmagnetic and resistant to concentrated nitric acid
  - one of the few that are provable right off the bat
  - produced by spallation reactions, primarily by collisions between protons and O atoms
  - relatively common in the Earth's crust
  - safe to handle , but the dust released from fabrication are highly toxic
  - six times stiffer than steel and a third lighter than aluminum
* is the hazard that researchers can most easily tie to weapons production
  - next element in the first row
  - only stable light metal with a relatively high melting point
  - used as an alloying agent in the production of beryllium-copper
* is used in copper alloy used for springs, electrical contacts, and non sparkling tools
  - gyroscopes and computer parts
* is used in the ceramics industry
  - nuclear industry and in alloys for aircraft
  - industrially in the manufacture of light fixtures and certain ceramics
  - to harden nuclear weapons and in electrical circuitry
* light weight metal with wide application in modern technology.
* light, hard, grayish non-radioactive metal that is lighter than aluminum.
* lightweight metal used in the defense, automotive and electronics industries
* metal associated with atomic-weapons production that can cause terminal lung disease
  - found in nature, especially in beryl and bertandite rock
  - that creates a toxic dust that can linger in the air
* metal used in manufacturing nuclear weapons and has been known to cause lung disease
  - many nuclear applications
  - the defense, electronics, and automotive industries
* naturally occurring metal which is found in beryl and bertrandite rock.
* naturally-occurring material.
* never occurs as a free element, only as a compound.
* non-radioactive metal that provokes, in some people, a highly allergic lung reaction.
* plays a critical role in ensuring our health and advancing our world
  - an indispensable role in modern society
* rare chemical element associated with several metallic alloys used in atomic weapons.
* reacts with acids and with water to form hydrogen gas.
* slivery, very light metallic element.
* strong, lightweight metal used in nuclear bombs and other weapons
  - the defense, automotive, and electronic industries
  - to make nuclear weapons
* toxic and carcinogenic material that requires specialized handling
  - metal which can cause an incurable lung disease
* very light and strong metal used in nuclear weapons and experimental reactors
  - tough metal, and is used in alloys to strengthen the metal
  - toxic metal
