What happens when you react rubidium with water?

Rubidium: Rubidium sinks because it is less dense than water. It reacts violently and immediately, with everything leaving the container. Rubidium hydroxide solution and hydrogen are formed.

Is the brainiac alkali metals video fake?

Brainiac had broadcast dramatic footage of alkali metals exploding in water. But with so many people now able to review and scrutinize the show, suspicions that the explosions had been faked were soon raised and then confirmed.

Does rubidium react violently with water?

Like the other alkali metals (lithium, sodium, potassium, cesium and francium), rubidium reacts violently with water, oxidizes when reacting with oxygen, and ignites due to humidity in the air, so great care must be taken when working with the element.

Is caesium an explosive?

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 happens when you put francium in water?

The piece of francium would blow apart, while the reaction with water would produce hydrogen gas, francium hydroxide, and a lot of heat. The entire area would be contaminated with radioactive material.

Which metal will explodes in water?

For decades, science enthusiasts have delighted at the famously energetic way sodium and potassium explode on contact with water.

How do alkali metals react with water?

Alkali metals react with water to produce heat, hydrogen gas, and the corresponding metal hydroxide. The heat produced by this reaction may ignite the hydrogen or the metal itself, resulting in a fire or an explosion. The heavier alkali metals will react more violently with water.

How does rubidium react with cold water?

Why does rubidium react more violently with water than potassium?

Rubidium is below potassium which means its reaction with water will be more violent than potassium. This is because Rubidium’s outer single electron is further away from its nucleus compared to potassium.

Is rubidium an alkali metal?

rubidium (Rb), chemical element of Group 1 (Ia) in the periodic table, the alkali metal group. Rubidium is the second most reactive metal and is very soft, with a silvery-white lustre.

How does caesium react with 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.
