  • Conveniently barium, which is a soft silvery metallic alkaline earth metal, is never found in nature in its pure form, due to its reactivity with air or in water.
  • Atomic number.
  • Electron affinity The energy released when an electron is added to the neutral atom and a negative ion is formed.
  • Unlike barium sulfate, barium carbonate dissolves in stomach acid, releasing the poisonous barium to do its rather nasty but efficient work.
  • Listen to Barium Podcast Transcript :.
