Why does the element calcium react with water differently than magnesium, potassium and sodium, in a way that calcium looks opaque and cloudy in water and when phenlotphtahein is added it looks bright pink but how come the other elements don't look like that in water? what makes calcium look different in appearance?

When Ca reacts with water the product is Ca(OH)2 and that is less soluble than, for example, NaOH when Na reacts with water. Both will give a bright pink color with phenolphthalein.
