Log in. The halogens are in group 7 so they have seven valence electrons . All the discovered alkaline earth metals occur in nature.All the alkaline earth metals have two electrons in their valence shell, so they lose two electrons to form cations with a 2+ charge. The non-metals in this family react by gaining 4 extra electrons through the formation of covalent bonds (sharing bonds). Alkaline earth metals are group 2 elements with 2 valence electrons. 1, 5, 7. Valence electrons; Group 2 (II) (alkaline earth metals) 2: Groups 3-12 (transition metals) 3–12: Group 13 (III) (boron group) 3: ... Group 4 elements have 4 valence electrons. Alkaline Earth Metals.

How many valence electrons do the alkaline earth metals have? This tendency is called the octet rule, because each bonded atom has 8 valence electrons including shared electrons. All Of The Alkali Earth Metals Group 2 Have Two Valence. The alkaline earth metals are those in the same group as calcium; they have two valence electrons. All the alkaline earth metals have two electrons in their valence shell, so the energetically preferred state of achieving a filled electron shell is to lose two electrons to form doubly charged positive ions.
