One term would be buoyancy.
the ability to float with density is almost impossible
If its boyant or not.
Buoyant Force
density. A less dense object will float on a more dense liquid.
This would include the term "buoyancy", which is not limited to objects that float. An objects whose weight is less than the water displaced by it would float. But an object could become suspended below water by the upward force of bouyancy, which acts on all objects in liquid.
