Is the alkali metal more reactive than an alkaline-earth metal?

Yes, alkali metals are more reactive than alkaline-earth metals. All atoms want to have 8 electrons in their outer shells. Alkali metals have to give one electron away, where as alkaline-earth metals need to give two away which is less energetically favorable.


Why alkali metals are more reactive than alkaline earth metals?

All atoms want to do is make their valence shell full. In alkali metals they have all of their shells completely full except one valence electron. The alkali metals REALLY want to get rid of that electron, so they will react with many elements/compounds to get rid of that electron. In alkaline earth metals they have all of their shells completely full except for two valence electrons. They also want to get rid of those electrons but the alkaline earth metals are not as desperate to do so as the alkali earth metals which make the alkaline much less reactive than the alkali metals.


Alkali metal and alkaline earth metal have how many ionization energies?

Alkali metals (group 1 elements) have one valence electron. Hence have one ionization energy Alkaline earth metals (group 2 elements) have two valence electron. Hence have two ionization energy


Which member of alkaline earth metal is least reactive?

Look at any periodic table: Beryllium #4 Magnesium #12 Calcium #20 Strontium #38 Barium #56 Radium #88


Where are the alkali and alkaline earth metals located on the periodic table?

Alkali metals: Group 1 in the periodic table Alkaline earth metals: Group 2 Halogens: Group 17 Noble Gases: Group 18 You can easily find them if you look at a periodic table.

What are the key differences between alkaline earth metals and alkali 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.


In what ways do alkali metals and alkaline earth metals differ?

Alkali metals and alkaline earth metals differ in their reactivity and properties. Alkali metals are more reactive and have one electron in their outer shell, while alkaline earth metals are less reactive and have two electrons in their outer shell. Additionally, alkali metals are softer and have lower melting points compared to alkaline earth metals.


What are the key differences between alkali metals and alkaline earth metals?

Alkali metals are in Group 1 of the periodic table and are highly reactive, while alkaline earth metals are in Group 2 and are less reactive. Alkali metals have one electron in their outer shell, while alkaline earth metals have two. Alkali metals are softer and have lower melting points compared to alkaline earth metals.


Why do alkaline earth metals react less rapidly than alkali metals?

Alkaline earth metals have two outer electons. Alkali metals have one. It is more energetically favorable (easier) t oremove one electron than two making alkali metals more reactive than alkaline earths.


How does the density of the alkaline earth metal compare with alkali metal?

The density of alkaline earth metals is generally higher than that of alkali metals. This is because alkali metals have only one valence electron and are larger in size compared to alkaline earth metals, which have two valence electrons and are smaller in size. The higher density of alkaline earth metals is due to their more compact atomic structure.


How do the alkali metals differ from the alkaline earth 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.


Do all alkaline metals have 2 electron shells?

No. All the alkaline earth metals have 2 valence electrons, meaning they have two electrons in the outermost shells. No two alkaline earth metals have the same number of electron shells. Beryllium is the only one with two shells.


How are alkali metals different from alkaline 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.


What is the characteristics of alkaline?

* 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.


Alphabetically What are the first and last of the alkaline earth metals?

Alphabetically, the first alkaline earth metal is barium and the last is strontium.


How are alkaline earth metals different from alkali metals in terms of their properties and reactivity?

Alkaline earth metals have higher melting points and densities compared to alkali metals. They are less reactive and have two valence electrons, while alkali metals have one valence electron and are more reactive.


Are ions of alkali metals larger or smallest than ions of alkaline earth metals from the same period?

Ions of alkali metals are generally larger than ions of alkaline earth metals from the same period because alkali metals have only one outer electron, leading to a larger atomic radius and therefore a larger ion size compared to alkaline earth metals, which have two outer electrons.
