<span>Water molecules form a complex with metal ions (usually a 6-coordinate complex). And the high charge density on a metal ion draws electrons away from the water molecules, making the O-H bonds more polar than normal. This allows the dissociation of the protons, making solutions of most metal ions acidic</span>
Ca is -2
Be is stabilized
Ba is -4
Sr is -3
so it would be => Ba, Sr, Ca, Be
