Answer:

Lose electrons

Step-by-step explanation:

All the alkaline earth metals have two electrons in their valence shell, so they lose two electrons to form cations with a 2+ charge. In chemical terms, all of the alkaline metals react with the halogens to form ionic alkaline earth metal halides.
