▸ Discovery
Humphry Davy — electrolysis of molten barium salts · England · 1808
▸ Stellar origin
s-process in AGB starsSecond-peak s-process element — built by slow neutron capture in the helium-burning shells of dying low-mass stars.
▸ Reactivity
Burns green in flames; reacts vigorously with waterSole reason green fireworks are green. Less reactive than the alkali metals but more reactive than calcium.
▸ Applications
- Green fireworks and signal flares
- Barium sulfate radiography (GI tract imaging)
- Drilling-mud weight additive
- Glass-melting flux
▸ Curiosity
Green fireworks are barium fireworks — the element that gives 'America the Beautiful' its emerald flash in the night sky.
