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.

Which 2 groups of metals are the most reactive?
1. alkaline metals 2. alkaline earths metals
What are the oxidation numbers for the metal groups 1A 2A 3A?
Group 1 or alkali metals (+1 oxidation number). Group 2 or alkaline earth metals (+2 oxidation number).
Why are the alkaline earth metals less reactive hen the alkali metals?
The alkaline earth metals are in group 2 of the periodic table this means they have 2 electrons in each of their outermost energy 'shells'. The alkaline metals are in group 1 and only have 1 electron to lose in a reaction rather than 2. This means the alkaline metals react more readily.
What describes the alkaline metals?
The alkaline metals group is the group at the very left group on the periodic table. The elements in this group have only 1 electron in the outer shell, so they react very easily, with for instance water.
What are the reactive groups of fatty acids?
Group 1 the Alkali Metals and Group 2 the Alkaline Metals. Group 1 is more reactive than Group 2.The three major reactive groups of elements are the alkali metals, Alkaline Earth and halogens (these groups are labeled 1 or IA, 2 or IIA, and 17 or VIIIB respectively)
What is groups 1 and 2 in the periodic table called?
The group 1 is alled the alkali metals group.The group 2 is called the alkaline earth metals group.
Which 2 groups of metals are the most reactive?
1. alkaline metals 2. alkaline earths metals
What are the elements in group 1 of the PTE called?
Alkaline metals
Where are type two metals found on the periodic table?
Metals are found in group-1 and 2. Group-1 are called alkalis and group-2 are called alkaline earth metals.
Why is group 1 metals called alkali metals?
They're metals that form alkaline compounds when they react with water.
WHERE ON THE PERIODIC TABLE IS THE METALS?
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.
What are alkaline metal an alkaline earth metal and a transition metal?
Beryllium magnesium strantium calcium barium radium
Where are the alkali family?
Alkali metals: group 1 Alkaline earth metals: group 2
What are the oxidation numbers for the metal groups 1A 2A 3A?
Group 1 or alkali metals (+1 oxidation number). Group 2 or alkaline earth metals (+2 oxidation number).
What family in the periodic table is completely made up of metals?
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.
Why are the alkaline earth metals less reactive hen the alkali metals?
The alkaline earth metals are in group 2 of the periodic table this means they have 2 electrons in each of their outermost energy 'shells'. The alkaline metals are in group 1 and only have 1 electron to lose in a reaction rather than 2. This means the alkaline metals react more readily.
How are metals classified in periodic table?
Metals are placed in group 1 (alkali metals) and group 2( alkaline earth metals) of the Periodic Table.
