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.
How do the alkali metals differ from the alkaline earth metals?
alkali metals have one valence electron, whereas alkaline earth metals have two valence electrons.
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.
What is one property of alkaline metals?
All of the alkaline earth metals are naturally occurring and they share similar properties: they are all rather reactive metals under standard conditions.
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.
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.
What family does calcium belong to.?
Calcium is one of the alkaline earth metals in group 2 (or IIa) of the periodic table.
Why is there an earth in alkaline-earth metals?
These metals are natually found deep in the earth's crust. They are one of the few metals on the periodic table that aren't man- made or are not the result of two elements joining together.
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.
What is the important characteristic do the alkali and alkaline earth metals have in common?
they all have at least one electron
Elements with one to two electrons in the outer energy level?
Alkali and alkaline earth metals
