The Group 1 elements were given the name "alkali" (not alkaline) because they react with water to form hydroxide ions, creating a basic, or alkaline solution with a pH greater than 7.
For example: 2Na(s) + 2H2O ---> 2NaOH(aq) + H2(g)
As you move down the group, the reactivity increases. The reaction with water is exothermic and can ignite the hydrogen gas that forms in the reaction.
Alkali metals (Group 1) and alkaline earth metals (Group 2) are the most reactive groups of metals. They readily lose electrons to form ions and participate in chemical reactions with nonmetals to achieve a stable electron configuration.
in periodic table،there are many groups of elements. group 1 is called alkaly metals . Group 2 is called alkaline earth metal.
Group 1 or alkali metals (+1 oxidation number). Group 2 or alkaline earth metals (+2 oxidation number).
Group 2 metals are classified as alkaline earth metals because they share similar properties: they are shiny, silvery-white, relatively reactive metals with two electrons in their outer shell. They react with water to form alkaline solutions and are generally less reactive than the alkali metals in Group 1.
Alkali metals are found in Group 1 of the periodic table and are highly reactive, while alkaline earth metals are found in Group 2 and are less reactive than alkali metals.
Alkaline metals
Group 1 in the periodic table is called the alkali metals, and Group 2 is called the alkaline earth metals. These groups of elements share similar chemical properties due to the number of electrons in their outermost energy level.
Metals are found in group-1 and 2. Group-1 are called alkalis and group-2 are called alkaline earth metals.
Alkali metals (Group 1) and alkaline earth metals (Group 2) are the most reactive groups of metals. They readily lose electrons to form ions and participate in chemical reactions with nonmetals to achieve a stable electron configuration.
Metals are on the left side in periodic table. They are mainly present in group-1,2,13. Group-1 is alkali metals and group-2 is alkaline earth metals.Group 1 contains alkaline metals. Group 2 contains alkaline earth metals. And d block also contains metals.
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.

Alkali metals: group 1 Alkaline earth metals: group 2
in periodic table،there are many groups of elements. group 1 is called alkaly metals . Group 2 is called alkaline earth metal.
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.
Alkali and alkaline earth family are metals. They are in group-1 and 2. They have metallic properties.The 2nd family of the periodic table is completely made up of metals. They are called alkaline earth metals. Be,Mg,Ca,Sr,Ba are examples.
Group 1 or alkali metals (+1 oxidation number). Group 2 or alkaline earth metals (+2 oxidation number).
