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.

∙ 13y agoThe alkali metals are more reactive than the alkaline earth metals. The reactivity of both metals increases as we go down the Periodic Table. That means the most reactive members of the group will be found at the bottom. The alkali metals are Group 1 elements, and the alkaline earth metals are the Group 2 elements, and more information can be found by using the links below.

∙ 13y agoNo, The alkali metals are the most reactive of the metals, with most of the alkaline-earth metals not far behind..

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.
What are the reactions with alkali metals and water like?
1) Alkali metals are stored in oil to minimise reaction with oxygen or water, it's a physical barrier towards air but the alkali metals still gradually corrode a traces of oxygen and water diffuse through. The reaction of alkali metals with water gets more violent for elements lower in the group e.g. (Li < Na < K < Rb < Cs). Adding them to water will cause an explosion due to the extremely exothermic nature of reaction, and can be rather dangerous and some alkali metals can react violently with just moisture in the air. Most of the alkali metals float on the top of the water, depending on how big the alkali metal is determines the size of the reaction this is because they're less dense that water itself and also during the reaction the alkali metals give of hydrogen gas which is quite flammable. Alkali Metal + Water » Metallic Hydroxide + Hydrogen The francium would be like any other alkali metal, it would be very violent like the other alkali metals.
Why do halogens react so easily with Alkali Metals?
The electron configuration is why they react. The Alkali metals have one electron in their outer shell and to complete their outer shell need 7 more electrons. They can give, take or share electrons with other atoms. This is when the Halogens come in handy. The Halogens have 7 electrons in their outer shells, and need one more to complete the outer shell. These can react very easily because they have both the perfect amounts to fill their outer shells and become compounds. Other atoms with other amounts to become atoms not ions needs another element to react with. Hope this helps, Matt.
Does alkali has a pH of over 12?
Some do. But all alkali have a pH value of more than 7.
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.
Name an alkali metal that is more reactive than K Na or Li Name an alkali metal that is less reactive?
Hydrogen (H) is more reactive. Francium (Fr) is less reactive.
How does the reactivity of an alkaline earth metal compare with that of alkali metal in the same period?
The alkali metals are more reactive.
Would a metal in the boron family or alkali metal be more reactive?
A metal in the alkali metal family has one valence electron where as a metal in boron family has three valence electrons. It is easy to remove one valence electrons than three. So alkali metals will be more reactive.
Which metal is more reactive than magnesium?
All the alkali metals.
What is the more reactive metal Cs or Na?
'Cs' ( Caesium )is the more reactive metal. Both metals are in Groujp (I) , The alkali metals. On going down from lithium to francium , group(I) metals become more reactive.,
What is the meaning of highly reactive metal?
alkali metal. This means it generates and allows more energy to flow throught it
What metal is alkali metal?
This is the first column in the Periodic Table. There are six metals that are "Alkali Metals" and six that are "Alkali Earth Metals". The Alkali metals are:LithiumSodiumPotassiumRubidiumCaesiumFranciumThese metals get more reactive as you go down the list...Hope I helped :D
What is the least reactive metal in the alkali metal group?
Lithium - As it is first in Group 1. Group 1 elemts become more reactive as you go down the group.
What alkali metal element is less reactive than calcium?
it is the lithium metal. it is less reactivated.
Which group of metals is more reactive the alkali metals or the alkaline earth metals?
The alkali metals are more reactive.
Which periodic table famiy is the most reactive?
The alkali metals are the most reactive of all groups on the periodic table. Some of the metals are lithium, potassium and sodium.
What element would be more reactive than magnesium?
Magnesium is more reactive than copper because if you study the periodic table, you will be able to find out that Magnesium is more reactive.Also, coins are made out of copper, they choose copper because it is cheap and extremely unreactive.Furthermore, I've done an experiment to find out that Magnesium is more reactive than Copper by putting both elements into Water/Acid.
