Many metals have a possible +2 oxidation state. Some metals do obtain it preferentially, however:
Group 12 metals (Zinc, Cadmium, Mercury) tend to have +2 oxidation states due to their electron configuration (d10, s2) retaining a full d orbital when 2 electrons are removed.
Group 8 metals (like Iron) also commonly have +2 oxidation states, possibly due to the 'half filled shell' effect.

What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
How many valence electrons in alkaline earth metals?
The alkaline earth metals are those in the same group as calcium; they have two valence electrons.
What is the name of the group of elements with two valence electron in each period?
The name of the group of elements with two valence electron in each atom is "alkaline earth metals."
What group in the periodic table has two valence electrons in their atoms?
The alkaline earth group has two valence electrons.
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.
What are metals that have 2 valence electrons?
alkaline earth metals (group 2 elements) have two valence electrons
How many valence electrons do the elements is group two have?
Group II elements (also called alkaline earth metals), have two valence electrons. To fill their outer shell, they therefore become ions with two positive charges, such as magnesium: Mg -> 2e- + Mg2+
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
How many valence electrons in alkaline earth metals?
The alkaline earth metals are those in the same group as calcium; they have two valence electrons.
Why are alkaline earth metals in group 2?
Because they have two valence electrons.
What is the name of the group of elements with two valence electrons?
Alkaline Earth 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 group have two valence electrons and make a 2 ion?
alkaline earth metals or group 2 elements have two valence electrons and make +2 ion.
What is the name of the group of elements with two valence electron in each period?
The name of the group of elements with two valence electron in each atom is "alkaline earth metals."
What group in the periodic table has two valence electrons in their atoms?
The alkaline earth group has two valence electrons.
How many valence electrons alkaline earth metal?
The alkaline earth metals are those in the same group as calcium; they have two valence electrons.
What are These metals have two electrons in their outer level?
The alkaline earth metals (group 2 on the periodic table) have two valence electrons (electrons in their outer level).
