alkali comes from an Arabic word 'alquili' which means plant ashes that is why they are named so
Group 2 elements in the periodic table are the alkaline earth metals.
Alkaline earth metals have two valence electrons, while alkali metals have one valence electron. Alkaline earth metals are harder and have higher melting points compared to alkali metals. Additionally, alkaline earth metals are less reactive than alkali metals.
Alkali metals are found in Group 1 of the periodic table and are highly reactive metals with one electron in their outer shell. On the other hand, alkaline earth metals are found in Group 2 and are also reactive but less so than alkali metals, with two electrons in their outer shell. Alkaline earth metals also have higher melting and boiling points compared to alkali metals.
Transition metals such as copper, silver, and gold are less reactive than alkali metals and alkaline-earth metals. These metals are less likely to react vigorously with water or air compared to alkali and alkaline-earth metals.
Alkaline earth metals have 2 valence electrons.
Alkali earth metals are named after their oxides, alkaline earth.
No. Metals are the best conductors because they have the least resistance. That's why they are used in batteries. Alkaline cells are named so because they use alkali metals in their compositions.
Alkaline earth metals were named "earth" to differentiate them from alkali metals, which were known to form alkaline solutions when reacting with water. The term "alkaline" was added to indicate they were compounds with a high pH.
* alkaline metals contain the higher melting and also the boiling points. * These metals are present in the earths crust which does not have a basic form. * Alkaline earth metals are distributed in structure which is named as rock. * These metals have density which is low. * Alkaline earth metals have low electron affinity and as wells as low electronegativity. * One of the basic characteristic is, it contains two electrons in their outer shell.
The five named groups from the periodic table are the alkali metals, alkaline earth metals, halogens, noble gases, and transition metals. Each group has unique properties and characteristics based on their electron configurations.
Alkaline metals and alkaline earth metals form their oxides when burnt. These oxides are base.

The alkaline earth metals are metals!
Group 2 elements in the periodic table are the alkaline earth metals.
Six alkali metals and six alkaline earths.
Alkaline earth metals have two valence electrons, while alkali metals have one valence electron. Alkaline earth metals are harder and have higher melting points compared to alkali metals. Additionally, alkaline earth metals are less reactive than alkali metals.
The alkali metals are generally more reactive than the alkaline earth metals. They form 1+ ions while the alkaline earth metals form 2+ ions. Alkali metal compounds tend to be more soluble in water than alkaline earth metals.
