It forms colorful connections, became the ?guiding element? of the Chernobyl disaster against its will and repeatedly confiscated as contraband by the police or customs - there is a lot to tell about cesium.
To the article about cesium on the website Fascination Chemistry.
Like sodium and potassium, cesium reacts violently with water. This video from the Periodic Videos series shows the reaction in ultra-slow motion.
Cesium belongs to group 1 of the alkali elements.
The elements of the 1st main group of the periodic table are called alkali elements.
The alkali elements or alkali metals include lithium, sodium, potassium, rubidium, cesium, and francium. Together with hydrogen, these form the 1st main group of the periodic table. Hydrogen is not one of the alkali metals because it has completely different properties under standard conditions, i.e. under normal pressure and room temperature.

The elements of the 2nd main group of the periodic table are called alkaline earth elements. These include beryllium, magnesium, calcium, strontium, barium, and radium.
