This is the generic reaction where "M" could represent any of the alkali metals.
2M + 2H2O --> 2MOH + H2
This really does not help anybody... at all. I asked for the metal not the formulaWell, the alkali metals reacting with water, which I took at school, are these:
Lithium (Li) ---> Slow bubbling (hydrogen gas produced)
Sodium (Na) ---> Faster bubbling (hydrogen gas produced)
Potassium (K) ---> Very fast bubbling, violent (hydrogen gas ignites)
Rubidium (Rb) ---> Violent (metal ignites)
see external link
Lithium, being the least reactive, just fizzes as it gives off hydrogen
Sodium, also fizzes and it melts into a small ball shape
Potassium, gives off hydrogen as it burns with a lilac flame
The alkali metal essentially replaces one of the hydrogen atoms in a water molecule, producing hydrogen gas and the corresponding metal hydroxide.
Depending on the specific metal the reaction can range from vigorous fizzing as with lithium to a violent explosion as with cesium.
Often the heat produced by the reaction is enough to ignite the hydrogen as it is emitted.
Should the alkali be strong, the alkali will become weak (pH number decreases).
Where M denotes any group 1 metal:
2M (s) + 2H2O = 2MOH (aq) + H2 (g)
it simply becomes ionized into a metallic cation and hydroxyl ion.
yes
Yes
Most metals do not react with water, especially at room temperature. It is easier to state which metals DO react with water. Those would be Li, K, Sr, Ca and Na. Those reacting with hot water (steam) would be Mg, Al, Zn and Cu. Most other metals do NOT react with water.
Alkali metals and earth alkali metals do react strongly with water.(Lithium, ..., Caesium) (Beryllium, ..., Barium)
They're metals that form alkaline compounds when they react with water.
Alkali metals reacts violently with water forming a hydroxide and hydrogen; alkali earth metals react with water but no so violent.Other metals doesn't generally react with water at room temperature.

Group 1 elements are known as alkali metals because they react with water to form alkali (or bases).

They don't
All alkali metals react violently with water.
Overall, transition metals have low reactivity with water. The alkali metals, however, react vigorously with water.
It will react vigourisly
