Pure sodium reacts violently with water, and sputters red hot sparks of molten metal when it does (see Mythbusters episode - Can elemental metals carry the same punch as a grenade?).

A substance that has high reactivity is what?
potassium sodium
Why can't sodium be extracted by reduction with carbon?
Because it isn't below carbon in the reactivity series. Sodium is so high on the reactivity series that the only effective way of extracting it is by electrolysis.
What is coppers reactivity with water?
Copper has extremely low reactivity with water which is why it is used to make water pipes.
Why does sodium not occur naturally in earth?
Sodium does occur naturally in the earth. However it is a very reactive metal and only occurs as compounds of sodium (e.g. sea salt NaCl).
What is the solubility of sodium in water?
Sodium doesn't dissolve in water, it reacts with water to form sodium hydroxide and hydrogen: sodium + water ----> sodium hydroxide + hydrogen
Could you use a sentence using the word reactivity?
yes, the abnormal reactivity of sodium in water produces a violent explosion.
What is sodium's chemical reactivity with water?
It reacr very violently.NaOH and H2 is given out
A substance that has high reactivity is what?
potassium sodium
What does this indicate about sodium's ability to form solutions?
high reactivity
Why can't sodium be extracted by reduction with carbon?
Because it isn't below carbon in the reactivity series. Sodium is so high on the reactivity series that the only effective way of extracting it is by electrolysis.
Is it impossible for an element to replace atoms of anothe element in a compound?
No. In a displacement reaction, that is exactly what happens. If an element low down in the reactivity series is in a compound, and you add an element that is higher placed in the reactivity series. The more reactive element will displace the less reactive element in the compound.Example:Copper Sulphate - Copper is low in the reactivity series and is in a compoundSodium + Copper Sulphate - Sodium is higher in the reactivity series than copper, and is in it's pure elemental form.Copper + Sodium Sulphate - The Sodium that is higher in the reactivity series has switched places with the Copper, which is lower in the reactivity series.FULL EQUATION:Sodium + Copper Sulphate --> Copper + Sodium Sulphate
Which form of sodium is more commonly found in nature sodium ion or sodium atoms?
The ions of course, due to its high reactivity
What is coppers reactivity with water?
Copper has extremely low reactivity with water which is why it is used to make water pipes.
sodium metal is kept under?
Sodium metal is usually kept under paraffin because of its high reactivity.
A sodium atom readily loses an electron in a chemical reaction What does this indicate about sodium's ability to form solutions?
high reactivity
What is the trend in the reactivity of the three alkali metals with water?
When an alkali metal is placed in water it will float and produce a gas like hydrogen which ignites in the presence of oxygen - producing a flame. The reactions get more and more vigorous as you move down the group. I may only be a grade 9 student but I think I may know this. Lithium, Sodium and Potassium are HIGHLY reactive to water. Lithium lightly sizzles when it reacts with water, and it produces a small amount of gas. Sodium reacts a little more, it bubbles on the water and creates a large amount of gas. Potassium has the most violent reaction to water, it actually pops when it comes into contact. It really explodes when you put it in water. It almost produces a red flame on top of the water. So you see, they are ordered by the level of reactivity. -------------------- Francium is the most reactive and electronegative chemical element; unfortunately is extremely rare and currently not available for chemical experiments. Also is very radioactive. The increasing order of reactivity with water is: Lithium, Sodium, Potassium, Rubidium, Caesium, Francium. The reactivity of chemical elements is controlled by their electronegativity; this parameter is decreasing from lithium to francium. The minimal electronegativity is equivalent to maximal reactivity.
What NOT a physical property of matter ductility color thermal conductivity reactivity of water?
reactivity of water is a chemical property
