yes but not in it's pure form
The standard atomic weight for cesium is 133. There are 3 other radioactive cesium isotopes that have atomic weights of 134, 135, and 137. Cesium 133 is the only one that is found in nature. The other isotopes are synthetic.
Cesium is found in group 1 of the periodic table.
The richest source of caesium in nature, at least in 1985, was a deposit of pollucite, a mineral that is hydrated mixed silica of aluminum and caesium, near Bernic Lake, Manitoba, Canada. The primary uses of the element are in photoelectric cells, as a hydrogenation catalyst, in atomic clocks, and in ionic propulsion systems for space vehicles.
Rubidium and cesium
Cesium is a naturally occurring element, and is found commonly on Earth. It is not a human creation, though certain specific isotopes may be.
Rubidium and Cesium. Rubidium was found to give off an emission spectrum of Ruby-Reddish.And Cesium with a bluish-purplish emission.
Groups 15, 18 and 1.
Cesium Sulfide
Since it is a metal, cesium will conduct electricity due to its mobile valence electrons, which are not atom-specific in metals. However, pure cesium doesn't even exist in nature because it so reactive.
Cesium compounds normally found are not considered particularly toxic, though, like anything else, an excessive amount of cesium is not good for you. It is said to make people irritable and cause spasm because it replaces potassium in the body. Metallic cesium reacts violently with water, and is not something you want to touch. Cesium isotopes leaked from nuclear power plants can be a serious problem because of their radioactivity.
The Alkali metals lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
