Navneord der begynder med A som er valideret

• atomic number 84 — Navneord – Engelsk ～ a radioactive metallic element that is similar to tellurium and bismuth; occurs in uranium ores but can be produced by bombarding bismuth with neutrons in a nuclear reactor
• atomic number 44 — Navneord – Engelsk ～ a rare polyvalent metallic element of the platinum group; it is found associated with platinum
• atomic number 28 — Navneord – Engelsk ～ a hard malleable ductile silvery metallic element that is resistant to corrosion; used in alloys; occurs in pentlandite and smaltite and garnierite and millerite
• atomic number 71 — Navneord – Engelsk ～ a trivalent metallic element of the rare earth group; usually occurs in association with yttrium
• atomic number 39 — Navneord – Engelsk ～ a silvery metallic element that is common in rare-earth minerals; used in magnesium and aluminum alloys
• atomic number 79 — Navneord – Engelsk ～ a soft yellow malleable ductile (trivalent and univalent) metallic element; occurs mainly as nuggets in rocks and alluvial deposits; does not react with most chemicals but is attacked by chlorine and aqua regia
• atomic number 26 — Navneord – Engelsk ～ a heavy ductile magnetic metallic element; is silver-white in pure form but readily rusts; used in construction and tools and armament; plays a role in the transport of oxygen by the blood
• atomic number 99 — Navneord – Engelsk ～ a radioactive transuranic element produced by bombarding plutonium with neutrons
• atomic number 64 — Navneord – Engelsk ～ a ductile silvery-white ductile ferromagnetic trivalent metallic element of the rare earth group
• atomic number 59 — Navneord – Engelsk ～ a soft yellowish-white trivalent metallic element of the rare earth group; can be recovered from bastnasite or monazite by an ion-exchange process
• atomic number 16 — Navneord – Engelsk ～ an abundant tasteless odorless multivalent nonmetallic element; best known in yellow crystals; occurs in many sulphide and sulphate minerals and even in native form (especially in volcanic regions)
• atomic number 105 — Navneord – Engelsk ～ a transuranic element
• atomic number 32 — Navneord – Engelsk ～ a brittle grey crystalline element that is a semiconducting metalloid (resembling silicon) used in transistors; occurs in germanite and argyrodite
• atomic number 6 — Navneord – Engelsk ～ an abundant nonmetallic tetravalent element occurring in three allotropic forms: amorphous carbon and graphite and diamond; occurs in all organic compounds
• atomic number 95 — Navneord – Engelsk ～ a radioactive transuranic metallic element; discovered by bombarding uranium with helium atoms
• atomic number 116 — Navneord – Engelsk ～ a radioactive transuranic element
• atomic number 20 — Navneord – Engelsk ～ a white metallic element that burns with a brilliant light; the fifth most abundant element in the earth's crust; an important component of most plants and animals
