What else can I help you with?
Why cant other alkali metals be substituted?
Alkali metal atoms can often be substituted by other atoms under the right conditions An example is Caesium in Caesium Chloride. By heating Caesium chloride with Calcium metal, caesium is substituted by calcium and the caesium can be distilled off at about 700oC under vacuum. This seems surprising, particularly given the higher reactivity of caesium, but the greater lattice energy of calcium chloride makes this the energetically preferred product over caesium chloride and drives the reaction. (As an aside, this was the most terrifying reaction that I ever did in a lab because of the high temperature caesium that is produced...)
What chemical properties would you expect caesium to have?
Caesium is freshly cut, it have a metallic shine, but this disappears rapidly due to reaction of exposed metal surface with oxygen in the air
When was caesium discovered?
Caesium was discovered in 1860.
Is caesium viscous?
Caesium is a solid metal.
Is caesium soluble?
Caesium react with water.
Is the reaction between caesium and water exothermic or endothermic?
The reaction between caesium and water is exothermic, meaning it releases heat. This is because when caesium reacts with water, it forms caesium hydroxide and hydrogen gas, releasing energy in the process.
What is the symbol equation for caesium reacting with water?
the formula for water is simply H2O (two hydrogens, one oxygen). The formula for cesium is Cs, it is a simple element. If you mean the reaction equation it is 2Cs + 2H2O --> 2CsOH + H2 The products are cesium hydroxide and hydrogen gas.

What type of bond is the bond between caesium and fluorine?
The bond between caesium and fluorine is an ionic bond. Caesium, a metal, donates an electron to fluorine, a nonmetal, resulting in the formation of ions with opposite charges that are held together by electrostatic forces.
What happens when caesium reacts with oxygen?
When caesium reacts with oxygen, it forms caesium oxide (Cs2O). This reaction is highly exothermic, releasing a significant amount of energy. Caesium oxide is a white solid that can react with water to form caesium hydroxide.
Balanced equation of reaction of caesium with iodine?
The balanced equation for the reaction of cesium with iodine is: 2Cs + I2 -> 2CsI
What metals can react explosively with cold water?
Rubidium, caesium and francium. Potassium will generate enough heat to ignite the hydrogen produced in the reaction but the reaction is not really explosive.
Would caesium with water be more reactive thank the reaction of sodium with water?
Yes, I saw a demonstration of this on a video once...
Can bromine and caesium be combined?
Sure, bromine and caesium can be combined to form a compound, but it's not a great idea unless you want to witness some explosive reactions. Bromine is a highly reactive halogen, while caesium is a highly reactive alkali metal, so mixing them together is like playing with fire...literally. Just be prepared for a potentially dangerous chemical reaction if you decide to go down that risky road.
What is the word equation for caesium reacting with water?
Caesium + water ------> Caesium hydroxide + Hydrogen
Is caesium soluble in water?
The cesium will react with the water and create an explosion. This is due to the fact that it is in the Alkali metals column, which all react with water. The reaction strength increases the further down the column you go Caesium (cesium in USA) metal reacts rapidly with water to form a colourless solution of caesium hydroxide (CsOH) and hydrogen gas (H2). The resulting solution is basic because of the dissolved hydroxide. The reaction is very exothermic. The reaction is so fast that if the reaction is carried out in a glass vessel, the glass container will shatter. Although not known for certain, the reaction is probably slower than that of francium (immediately below caesium in the periodic table). The reaction is faster than that of rubidium (immediately above caesium in the periodic table). 2Cs(s) + 2H2O → 2CsOH(aq) + H2(g) it blows up
