Is Cesium a metalloid?
Cesium is an alkali metal, along with lithium, sodium, potassium, rubidium and francium.
How do you know what family your element belongs to?
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
Is Cesium a main group element?
The alkali metals are silver-colored (caesium has a golden tinge), soft, low-density metals. These elements all have one valence electron which is easily lost to form an ion with a single positive charge….Properties.

What is a cesium atom?
Caesium (IUPAC spelling) (also spelled cesium in American English) is a chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature.
Is cesium a main group element?
What are some facts about cesium?
Facts About Cesium. Lepidolite crystal is a source of lithium, rubidium and cesium. Cesium is a rare, silver-white, shiny metal with brilliant blue spectral lines; the element’s name comes from “caesius,” a Latin word meaning “sky blue.”. It is the softest metal, with a consistency of wax at room temperature.
Is cesium on the periodic table?
Cesium (Cs) is a chemical element in the periodic table with atomic number 55 discovered by Fustov Kirchhoff and Robert Bunsen in the year 1860.
Is cesium a metal?
Cesium (Cs) is a waxy, silvery-gold metallic element that is the softest of all metals. Cesium is one of three metals ( gallium and mercury) that are liquid at or near room temperature. Cesium is a very reactive metal, that when mixed with cold water, produces an explosive reaction.
Is cesium mined?
Trace amounts of cesium are found in a handful of minerals, according to Minerals Education Coalition. It is mainly mined from pollucite (ranging from approximately 34 to 42 percent, according to the U.S. Geological Survey ), as well as in lepidolite as an impurity. Cesium is mainly mined in Canada and Zimbabwe.
