Ice is expanded water, so is less dense that the water it floats in. Being less dense, and so lighter, the ice will float on water with at least one third (approximately) above the surface
No, Fimo does not float in water. It is a type of polymer clay that is dense and sinks in water.

Sulfur sinks in water because it is denser than water.
Float
No, ironwood does not float. It is a dense and heavy type of wood that sinks in water.
No, it is a metallic rare earth element that is denser than water and thus sinks.
Cesium metal will float on water as its density is lower than that of water, causing it to float.
Diamonds do not float.
If it sinks in water, then it is more dense than water.
No, apatite does not float on water because it has a higher density than water. Apatite sinks in water due to its composition and density.
Chromium sinks in water as it has a higher density than water.
