How many outer electrons are in alkali earth metals?
Two!
How many valence electrons do alkaline earth metals have?
The alkali earth elements have TWO valence electrons.
How many alkali earth metals are there?
6: beryllium, magnesium, calcium, strontium, barium, and radium.They are generally referred to as alkaline earth metals.
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.

How many Alkaline and Alkali Metals are there?
Six alkali metals and six alkaline earths.
How many valence electron does alkali metals have?
Alkali metals have one valence electron.
How many valance electrons has alkali metals?
1 valence electron in alkali metals.
How many valence electrons do the alkali metals have?
Alkali metals have 1 valence electron.
Do the alkali metals have the ability to tarnish?
By forming their oxides, the alkali metals tarnish very quickly with respect to many other 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
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
