Why are the alkaline-earth metals less reactive than the alkali metals?

Alkaline-earth metal have two electrons in there outer shell, so only need to lose one to form a stable electron arrangement.
Alkali metals have one electron in there outer shell - so they need only lose one to form a stable electron arrangement

Are gold and platinum reactive metals?
Gold and platinum are less reactive metals but not absolutely non-reactive.
What are the elements called in the first group of the periodic table that have one outer shell electron and is extremely reactive?
The elements in the first group of the period table which have one electron in their outer shells and react extremely well are also known as the alkali metals. These elements are Hydrogen, Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium.
Is gold a non reactive metal?
Gold is a less reactive metal but not non-reactive; all metals are reactive.
What is a very reactive non metals?
The highly reactive non-metals are in the halogen group. They just need one more electron to fill the octet. Therefore they are highly reactive. For example fluorine and chlorine. And the highly reactive metals are placed in the first group (alkali metals). For example Sodium and potassium.
What kind of elements has less than 4 valence electrons?
Boron group, transition metals, alkaline earth metals and alkali metals are listed in the Periodic Table are having less than four valence electrons
Are alkali metal and alkaline earht metals similar?
The alkali earth metals act in a similar but slightly less reactive way to alkali metals
Metals that are less reactive than alkali metals and alkaline-earth metals are?
Almost all the rest of the metals.
Metals that are less reactive than alkali metals and alkaline-earth metals are called?
I believe that the answer you are looking for is Transition Metals.
Is noble gases metals that are more reactive than the transition elements but less reactive than the alkali metals?
No, the noble gasses are nonmetals that are less reactive than all other elements.
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 are alkali metals more reactive than transitional metals?
Groups 3-12 do not have individual names. Instead, all of these groups are called transition metals. The atoms of transition metals do not give away their electrons as easily as atoms of the Group 1 and Group 2 metals do. So, transition metals are less reactive than alkali metals and alkaline-earth metals are.
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 are denser harder have higher melting points and are slightly less active than alkali metals in the same period?
Alkali metals are very chemically reactive, are not dense or hard metals and have low melting points.
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.
What generalizations can you make about transition metals?
Transition metals are less reactive than alkali metals and alkaline-earth metals. They tend to be shiny and conduct thermal energy well.Hope this helps!~ I first I didn't get it either. : )
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 ways you catorgorize the elements in the periodic table?
the elements are categorised into firstly metals and non metals. metals are on the right and middle and non metals are on the left. Then they are categorised according to reactivity, for example the first column on the far left are all alkali metals, bar helium, which are highly reactive to water and air. Then the next column is of alkali earth metals, which are like alkali metals but are found more naturally are are less reactive. here's a link to a site that might help because i'm not brilliant at explaining
