more reactive, the elements of the first column increase in reactivity as you go down

Is francium the largest and most reactive metal?
Francium (Fr) should, based on its position in the periodic table, be the most reactive metallic element. However, fluorine is the most reactive element generally.
How many compounds are in the element potassium?
NONE!!! You have pitched the question the wrong way around. It should be 'How many compounds contain the element potassium?' The answer is hundreds if not thousands. Here are a few compounds containing potassium Potassium oxide (K2O) Potassium hydroxide (KOH) Potassium Carbonate (K2CO3) Potassium chloride (KCl) Potassium permanganate ( KMnO7) Potassium ethanoate (CH3COOK) et.seq.,
Is potassium acidic or basic?
a single element can NOT be classified as an acid or a base, since an acid needs to have an H+ ion in its formula, and a base should contain OH-, so it should be a compound.
Is caesium soluble in water?
The cesium will react with the water and create an explosion. This is due to the fact that it is in the Alkali metals column, which all react with water. The reaction strength increases the further down the column you go 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. The reaction is so fast that if the reaction is carried out in a glass vessel, the glass container will shatter. Although not known for certain, the reaction is probably slower than that of francium (immediately below caesium in the periodic table). The reaction is faster than that of rubidium (immediately above caesium in the periodic table). 2Cs(s) + 2H2O → 2CsOH(aq) + H2(g) it blows up
What is the pH of potassium Chloride?
Pure potassium chloride solution should have a pH about 7.
Which element combines elements easiest with potassium?
Potassium is most reactive with the element Oxygen. However, it should be noted that it is most reactive with a non-element: Water.
What is a reactive metal in table salt?
Metallic character of an element is determined by its ease to lose electrons that is the force of attraction put on the shells by the nucleus should be less. Therefore elements with greater atomic number and present in the last period to the left side is considered to be more metallic. so reactive metals are those that easily lose electrons and react with other elements. eg francium , caesium radium barium
What reacts vigorously with water?
Among many, Sodium. Potassium, even more so.
Why is francium the most reactive chemical?
It should be noted that francium is not the most reactive element, but is the most reactive metallic element. Francium has the lowest electronegativity and the greatest electropositivity; the chemistry of francium is practically unknown today.
What is caesium?
Most likely Ceasium is a common misspelling of the name for the 55th element: Caesium or Cesium, symbol Cs.(The misspelling can be understood when written phonetically after the correct pronounciation: "see-zee-əm" . It should not be pronounced as "kee-zee-əm" as would be expected from -the correct- spelling 'CAE...')
Francium will bond with what other element?
The chemistry of francium is not experimentally known; it is only estimated. Francium should be have properties similar to caesium.
Is francium the largest and most reactive metal?
Francium (Fr) should, based on its position in the periodic table, be the most reactive metallic element. However, fluorine is the most reactive element generally.

Would you expect cesium to be more or less reactive than potassium?
AnswerDespite the fact that you could look it up that cesium is indeed more reactive than potassium, you could also take into account the periodic trends. One of these trends is that metals tend to be more reactive as you proceed down a group/family and as you move to the left of the table. Since both cesium and sodium are members of the alkali metals, cesium should be more reactive of the two.
Does potassium react more than sodium?
No, sodium reacts more than potassium. More violently also. The electrons surrounding the sodium atom are closer together (tighter to the nucleus of the atom) and this results in more energy needing to be used to rip them off. To test this, you could get a bucket of water (H20) and put some pure potassium in it. The try some pure sodium. Watch which one will have a greater reaction. (The potassium should fume, possibly ignite. The sodium should on the other hand ignite then explode). Lithium has an even greater reaction than these two. As you work your way up the alkali metals group in the periodic table (Group or column 1) the reactions intensify between the metals and solutions, such as water. Li>Na>K>Rb>Cs>Fr It works like this for reactions of almost any element. The element directly above should be more reactive than itself.
What element does francium bond with?
The chemistry of francium is not experimentally known; it is only estimated. Francium should be have properties similar to caesium.
How much is Caesium worth?
The standard price for pure Caesium is $100 per gram. This is due to the fact that Caesium is very dangerous. the melting point of Caesium is around 82 F. As a result it will catch fire. It is not to be talking kindly, people should under no circumstance play with this unless they are a fully certified chemist.
