the material which has higher density than water will immerse in water,,,so calcium ND magnesium may have lower density than water.,density=mass by volume,,,,hope it helps

But just know Ca and Mg both are metals and metals react with water and H2 gas is liberated
So, these metals float on the surface due to accumulation of H2 gas bubbles under the metal surface which provide sufficient surface area to float
