What happens when francium reacts with 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.
What products are formed when francium reacts with water?
Francium would react with water by this equation: 2Fr + 2H2O –>2FrOH + H2 The products here are francium hydroxide and hydrogen gas.
What is the relationship between an alkali metal’s electron configuration and the metal’s reactivity when added to water?
The alkali metals (group 1) are very reactive, readily form ions with a charge of 1+ to form ionic compounds that are usually soluble in water, and react vigorously with water to form hydrogen gas and a basic solution of the metal hydroxide….Chemistry End of Chapter Exercises.

What does francium decay into?
radium
Francium can be produced by bombarding thorium with protons or by bombarding radium with neutrons. Francium’s most stable isotope, francium-223, has a half-life of about 22 minutes. It decays into radium-223 through beta decay or into astatine-219 through alpha decay.
What happens if you drop caesium?
The caesium sample they used was kept in liquid nitrogen before it was dropped into the water from about a metre above. When caesium makes contact with water, it reacts very rapidly, and forms a colourless solution of caesium hydroxide (CsOH) and hydrogen gas (H2).
What happens when francium reacts fluorine?
1 Francium. Because francium is known to be a real alkali metal, its reaction with fluorine should lead to the formation of FrF.
What happens when Caesium is added to water?
Reaction of caesium with water 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.
How does sodium react with water?
When sodium is added to water, the sodium melts to form a ball that moves around on the surface. It fizzes rapidly, and the hydrogen produced may burn with an orange flame before the sodium disappears.
Why is francium more reactive than lithium?
Francium is an alkali metal in group 1/IA. All alkali metals have one valence electron. As you go down the group, the number of electron energy levels increases – lithium has two, sodium has three, etc…, as indicated by the period number. This makes it easier to remove the electron and makes the atom more reactive.
What would happen if francium reacts with fluorine?
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.
What happens when you put francium in water?
Rubidium ignites with a red flame. Cesium releases enough energy that even a small piece blows up in water. Francium is below cesium on the table and would react more readily and violently. This occurs because each of the alkali metals is characterized by having a single valence electron.
Why does francium have a strong exothermic reaction?
The reason for the strong exothermic reaction is because francium is an alkali metal. As you move down the first column of the periodic table, the reaction between the alkali metals and water becomes increasingly violent, as follows: A small amount of lithium will float on water and burn.
What happens in a reaction between francium and caesium?
If you were able to get a visible amount of francium, we would expect it to react very similarly to caesium, which is immediately above it in the periodic table. This is a very violent reaction, which you can find as videos on the internet. However much modern chemistry is less visibly exciting (though the results are exciting for the chemist).
How is francium prepared on the periodic table?
Francium is element number 87 on the periodic table. The element can be prepared by bombarding thorium with protons and an extremely small amount occurs naturally in uranium minerals, but it is so rare and radioactive that there has never been enough of it to actually see what would happen if a piece was dropped into water.
