Each language has a different word for caesium but frequently the spelling is very similar.
2 Cs + 2 H2O → 2 CsOH + H2 caesium+water = caesium hydroxide+hydrogen
these are in alkali metal groupsso the names are hydrogen, lithium, sodium, potassium, rubidium, caesium
No...Caesium and Francium are both Alkali metals. They cannot bond ionically with each other.
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...)
Only caesium has the same properties as caesium. There are other elements which have some similar properties.
Caesium (Cs), since has the lowest electronegativity
Caesium + water ------> Caesium hydroxide + Hydrogen
Yes, Francium has a couple older names. The first time it was discovered, it was called "eka-caesium." The second name was "moldavium."
Caesium is a soft metal
Caesium react with water.
Caesium is a solid metal.
Caesium was discovered in 1860.
