The alkali metals sodium, potassium, rubidium, and cesium ignite on contact with water.
I believe that you think to alkali metals (ex. sodium).
Throw water on it. The logical answer.
It reacts strongly in water and bursts into flames when exposed to air.
It either explodes or bursts up in to flames.
Potassium is the only metal (alkali metal) where a flame is present. Lithium and sodium fizz but there is no flame. Caesium, francium and rubidium all explode on contact with water.
Once the Potassium hits the water, it bursts into flames. Very cool! Elemental potassium is a soft silvery-white alkali metal that oxidizes rapidly in air and is very reactive with water, generating sufficient heat to ignite the hydrogen emitted in the reaction.
sodium, potassium, rubidiumSodium reacts very quickly with water. All Alkali metals, the first column of the periodic table excluding Hydrogen (H), react violently with water. The lower the row, the more explosive the reaction.
No, I can only think of one example, sodium (not salt because salt is sodium chloride) is clay like metal that also bursts into flames and explodes when it comes into contact with water.
It reacts strongly in water and bursts into flames when exposed to air. =] and it is the third most reactive alkali metal
Diamond can disintegrate if heated enough and will give off carbon dioxide on water and disappear Any of the alkaline metals will burst into flames
They are very reactive. They can react violently or explosively with water, usually catching fire soon after contact. They react with moisture and air to produce strong bases that can cause serious chemical burns. The two most reactive of the metals, rubidium and cesium, burst into flames on contact with air.
A soft, light weight metal called sodium, which we never see. It bursts into flames in air and can even burn under water.
Sodium and potassium are the most common metals that explode on contact water. Rubidium and cesium will also explode in water, but they are harder to obtain.
Neither of them are rare earth metals, meaning they they do not burst into flames when they come into contact with water. They do have different electronegativities, meaning that in the presence of an acid, one will accept the other's electrons (through a long chain of reactions), and are metals to allow easy conduction of electrons.
To keep them from coming in contact with water or air. Metals such as sodium and potassium react rapidly with air and violently with water.
No. Table salt is sodium chloride. Sodium on its own is a completely different substance that bursts into flame on contact with water.
It happens when metals come in long term contact with water and oxygen
as you go down there are more electrons on the outer shells which makes them more reactive when in contact with water
group 1 or alkali metals
Pure sodium will erupt into flames, yes. This is because alkali metals are extremely reactive. That's why it's usually stored in oil, away from water.
because when sodium comes in contact with water it bursts into sparks. plus sodium is VERY soft metal, that's what she said
Contact of alkali metals with water produce Hydrogen gas. Contact of active metals with a strong acid produce Hydrogen gas. Elecrolyses of chloride salts produce Chlorine gas.
Yes all group one elements (alkali metals) are explosive when they come into contact with water.
The kerosene prevents the sodium from coming in contact with water and air. Sodium is very reactive. If it touches air it will oxidize, ruining the sample. If it touches water it will burst into flames.
The alkali metals release hydrogen when in contact with water: 2 Na + 2 H2O -> 2 NaOH + H2
