Is cesium a physical or chemical property?

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 solid liquid or gas?

Cesium is a chemical element with symbol Cs and atomic number 55. Classified as an alkali metal, Cesium is a solid at room temperature.

Is cesium malleable or brittle?

Cesium is an alkali metal, along with lithium, sodium, potassium, rubidium and francium. Alkali metals are highly reactive, have one electron in their outer shell, and do not occur freely in nature, according to ChemicalElements. These metals are also very malleable, ductile and good heat and electrical conductors.

Is cesium soluble in water?

Cesium salts and most cesium compounds are generally very water soluble, with the exception of cesium alkyl and aryl compounds, which have low water solubility.

Does cesium react with water?

Cesium: Cesium explodes on contact with water, possibly shattering the container. Cesium hydroxide and hydrogen are formed.

Is cesium Magnetic yes or no?

Other materials considered strongly paramagnetic include iron ammonium alum (66), uranium (40), platinum (26), tungsten (6.8), cesium (5.1), aluminum (2.2), lithium (1.4) and magnesium (1.2), sodium (0.72) and oxygen gas (0.19).

Can you touch cesium?

If you were to breathe, eat, drink, touch, or come close to large amounts of radioactive cesium, cells in your body could become damaged from the radiation that might penetrate your entire body, much like x-rays, even if you did not touch the radioactive cesium.

Why does cesium explode in water?

When caesium makes contact with water, it reacts very rapidly, and forms a colourless solution of caesium hydroxide (CsOH) and hydrogen gas (H2). This reaction is so fast, that if you tried pouring water into a test tube containing caesium (don’t do it), the glass container would shatter all over the place.

Which is the softest metal in the world?

* Caesium is the softest metal with the Mohs hardness of 0.2.

What are 3 interesting facts about cesium?

  • Atomic number: 55.
  • Atomic weight: 132.90545196.
  • Melting point: 301.59 K (28.44°C or 83.19°F)
  • Boiling point: 944 K (671°C or 1240°F)
  • Density: 1.93 grams per cubic centimeter.
  • Phase at room temperature: Solid.
  • Element classification: Metal.
  • Period number: 6.

Is cesium reactive with light?

Additionally, cesium is very photoelectric, meaning it loses electrons when struck by light. It is used for atomic clocks, photoelectric cells, and as a catalyst promoter. As a catalyst promoter, it increases the activity of other metal oxides and the hydrogenation of organic compounds.

Is caesium flammable?

FIRE HAZARDS * Cesium is a FLAMMABLE LIQUID or SOLID which MAY IGNITE SPONTANEOUSLY IN AIR.

How explosive is cesium?

Caesium metal is highly reactive and very pyrophoric. It ignites spontaneously in air, and reacts explosively with water even at low temperatures, more so than the other alkali metals (first group of the periodic table).

What makes cesium unique?

It is the most electropositive and most alkaline element. Cesium, gallium, and mercury are the only three metals that are liquid at or around room temperature. Cesium reacts explosively with cold water, and reacts with ice at temperatures above -116°C. Cesium hydroxide is a strong base and attacks glass.

What are cesium used for?

The most common use for caesium compounds is as a drilling fluid. They are also used to make special optical glass, as a catalyst promoter, in vacuum tubes and in radiation monitoring equipment. One of its most important uses is in the ‘caesium clock’ (atomic clock).

Is cesium toxic?

High levels of radioactive cesium in or near your body can cause nausea, vomiting, diarrhea, bleeding, coma, and even death. This may occur after nuclear accidents or detonation of atomic bombs.

Is cesium harmful to humans?

Exposure to stable cesium is not considered to be a major public health threat since it is mildly poisonous and has limited use. However, medical providers may prescribe a compound called Prussian blue, which can remove stable cesium from the body in waste matter. In most cases, cesium leaves the body in urine.

What is the price of cesium?

In 2020, the price for a cesium-plasma standard solution (10,000 micrograms per milliliter) was $77.80 for 50 milliliters and $119.00 for 100 milliliters, and the price for 25 grams of cesium formate, 98% (metal basis), was $41.40.

Is cesium a heavy metal?

Caesium, being one of the heavier alkaline metals, is also one of the most reactive and is highly explosive when it comes in contact with water (even cold water, or ice). Caesium hydroxide is an extremely strong base, and can attack glass. Caesium compounds are encountered rarely by most people.

Is caesium the most reactive metal?

Francium is most reactive element in periodic table. However, francium is artificial or only few quantities have produced right now, so after the francium, cesium is most reactive metal.

Is cesium a metal or nonmetal?

cesium (Cs), also spelled caesium, chemical element of Group 1 (also called Group Ia) of the periodic table, the alkali metal group, and the first element to be discovered spectroscopically (1860), by German scientists Robert Bunsen and Gustav Kirchhoff, who named it for the unique blue lines of its spectrum (Latin …

What happens if u drop cesium?

But toss it in water, or just leave it exposed to the ambient air, and it will self-ignite to send up purplish-pink chemical flames. Even if the stuff is cooled to minus 177 degrees Fahrenheit, dropping it in water will cause an explosive reaction with the oxygen in the liquid.

What happens if caesium reacts with air?

Reaction of caesium with air The resulting surface is bright and shiny. However, this surface soon tarnishes because of reaction with oxygen and moisture from the air. If caesium is burned in air, the result is mainly formation of orange caesium superoxide, CsO2.

What is the most explosive element in the world?

Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state.

Does cesium react with oxygen?

Cesium tarnishes slowly in air as it react with both oxygen and water in the air. If burned in air, the result is mainly formation of the orange cesium superoxide, CsO2.
