The alkali metals and water form the alkali metal hydroxide and hydrogen gas. 2Alk + H2O => 2Alk OH + H2^ Note that there is a "2" in front of the "Alk" (which is alkali metal). All the alkali metals are in Group 1 of the Periodic Table, and they all have a +1 valence. They will combine with water in a 2-to-1 ratio. The result will be 2 of the alkali hydroxide molecules and H2 with the "up arrow" to indicate that hydrogen gas is being liberated in the reaction.
Group 1 metals are called alkali metals because they form alkaline solutions (pH greater than 7) when they react with water. They are highly reactive and easily lose their outermost electron to form positive ions, which makes them behave in a similar manner to the alkaline earth metals.
They metals are stored in oil to minimize the reactivity with air. When alkali metals react with air, they quickly tarnish after begin cut, they burn easily.
Yes. Explosively. They will react to produce a metal hydroxide, hydrogen gas, and a bunch of heat. Here's the equation for sodium (Na, #11) reacting with water: 2Na + 2H2O --> 2NaOH + H2 The reaction is violently exothermic to the point where the hydrogen gas ignites and explodes, which itself is a separate reaction: 2H2 + O2 --> 2H2O
They are actually called the alkali metals. They are called the alkali metals because many of the compounds they form are bases (alkaline) and in pure form they will react with water to produce strong bases.
Most transition metals are insoluble in water with the exception of some transition metal ions that form soluble complexes, such as copper(II) ions. Transition metals tend to form insoluble hydroxides or oxides when they react with water.
Group 1 elements are known as alkali metals because they react with water to form alkali (or bases).
Alkali earth metals react with oxygen to form basic oxides.

Alkali metals: Li, Na, K, Rb, Cs, Fr.
Such metals are Sodium and Potassium (and all the alkali metals).
They metals are stored in oil to minimize the reactivity with air. When alkali metals react with air, they quickly tarnish after begin cut, they burn easily.
Alkali metals react vigorously with water, producing hydrogen gas and forming alkaline solutions. They react with oxygen to form oxides, and with noble gases they can form compounds under certain conditions, although the reactivity is not as intense as with water or oxygen.

The alkali metals are found in period 1 of the periodic table. They are soft,silver-coloured metals that react violently with water to form basic solutions. The most reactive alkali metals are cesium and francium.
The metals that lose one electron when they react with water to form alkaline solutions are group 1 and group 2 metals such as lithium, sodium, potassium, calcium, and magnesium. These metals are highly reactive and readily donate their outermost electron to form cations that react with water to produce alkaline solutions.
