they all do.
2 valence electrons are in iridium because iridium is a transition metal. Most transitions metal would have 2 valence electrons because the group before the transition metals are the alkaline-earth metals which contains 2 valence electrons in that group making the transition metals have 2 valence electrons.
We know that the alkaline earth metal magnesium has twovalence electrons. Just like all the other alkaline earth metals.
That compound is beryllium oxalate. Beryllium, an alkaline earth metal, has two valence electrons, which it will lose to the oxalate polyatomic ion.
The ionic charge depends on the number of valence electrons. Alkali metals, alkaline earth metals and aluminium have 1, 2 and 3 valence electrons respectively and will hence form ions with +1, +2 and +3 charges respectively.
The alkaline earth metals are those in the same group as calcium; they have two valence electrons.

Magnesium, an alkaline earth metal, has two valance electrons. The symbol of magnesium is, Mg ----
alkaline earth metals such as Be, Mg, Ca, Sr, Ba, Ra

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
None. The alkaline earth metal isotope with the fewest neutrons would be beryllium-7 with three neutrons and a half-life of 53 days.
