barium
Green firework component
Barium is a soft, silvery metallic element that reacts readily with air and water.
Its compounds appear in various industrial applications.
In medicine, a barium swallow or barium enema uses a chalky barium sulfate solution to coat the digestive tract, making it visible on X-rays: The doctor ordered a barium study to check for ulcers.
