Metals lose electrons in a chemical reaction.
No. Alkali metals have one valence electrons. Halogens have 7 valence electrons.
one valence electrons
Alkaline earths have 2 valence electrons.
Alkaline earth metals have 2 valence electrons.
The alkaline earth metals are those in the same group as calcium; they have two valence electrons.
alkaline earth metals (group 2 elements) have two valence electrons
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
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.
The alkali earth elements have TWO valence electrons.
Alkali Earth metals have a single valence electron, and are found in the first group.
metals can conduct electricity, the valence electrons of nonmetals cannot roam freely
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
