🔬 Cesium Properties
Cesium is soft, ductile, and golden-hued. It melts at 28.5°C (83.3°F), just above room temperature, and reacts explosively with water.
🧪 How Was Cesium Discovered?
In 1860, German chemists Robert Bunsen and Gustav Kirchhoff identified Cesium via spectroscopy in mineral water, naming it for its sky-blue spectral lines (Latin "caesius").
⚡ Uses of Cesium
