To ensure purity and safety, Rubidium (Rb) must be kept in a dry mineral oil or in a vacuum. It needs to be stored in this way because it is highly reactive with air and water.

What shiny metal explodes on contact with air or water?
Rubidium and caesium
What is the reactivity of caesium?
Caesium is the 5th element in group I of the periodic table. It is an alkali metal, and they become more reactive as you go down the group from lithium to sodium to potassium etc. So we would expect that caesium is highly reactive, even more reactive than rubidium.
Which substance has a chemical formula with the same ratio of metal ions to nonmetal ions as in potassium sulfide?
lithium, sodium, caesium, rubidium sulphides: Me2S.
Cesium why blue in alkali?
Caesium metal is gives a bright blue solution when dissolved in liquid ammonia. The dissolving is believed to cause the production of caesium ions and a free electron. a similar blue colr is produced by sodium, potassium and rubidium. In aqueous alkali solutions caesium ion is colorless and therefore unless the anion is colored the solution is colorless.
What are Potassium's brothers and sisters?
Potassium is an alkali metal, other memebers of the family are lithium, Li; sodium, Na; rubidium, Rb; caesium, Cs; francium, Fr

is gold the only metal that sinks in water?
No, rubidium and caesium can also sink in water
Which element has the same properties as cesium?
Only caesium has the same properties as caesium. There are other elements which have some similar properties.
How do you predict that francium would react?
The chemical reactions of francium are probably similar to the reactions of caesium or rubidium.
What elements in addition to lithium makeup the alkali metal family?
Sodium, Potassium, Rubidium, Caesium, and Francium
