alkali metal include alkali metal include:-


hydrogen

lithium



sodium

Potassium

etc


when they react with are they form corresponding oxide:-


for example:-


Lithium oxide li2O



sodium oxide Na2O

hope it helps :D



thanks

Answer 2

HEYA!!!!

Here is your answer :
______________________________



Alkali metals : Metals like Lithium, Potassium, Sodium are called as Alkali metals. Alkali metals are high reactive. They react very fast with hydrogen and Oxygen.

~ when they react with oxygen then form Alkali oxides.

~ These alkali oxides are usually white in colour.

~ When they dissolve in water they form Alkali hydroxide.

~ When sodium reacts with oxygen then the following reaction takes place :

Sodium + Oxygen ----> Sodium oxide

4 Na + O2 ---------> 2Na2O


~ When potassium reacts with Oxygen then the following reaction takes place :

Potassium + Oxygen ----> Potassium oxide

4K + O2 -----> 2K2O

~ When Lithium reacts with oxygen then the following reaction takes place:

Lithium + Oxygen -------> Lithium oxide

4Li + O2 --------> 2Li2O
