It is not true; osmium is more dense.
FALSE. There are probably 15 elements more dense than mercury. A few examples would be Osmium, Platinum, and Gold, just to name a few.
Look at the density of each substance. Iron is less dense than mercury, so yes, it will float.
No, rocks are denser than mercury, so they would sink in mercury. Mercury is a very dense liquid at room temperature, so objects that are less dense than mercury will float on it.
There's no correlation between the composition of a substance and its density. Pure ethanol is less dense than potato-leek soup, but pure mercury is more dense. Potato-leek soup is less dense than pure mercury, but concrete is more dense.
At "normal" temperatures, Mercury is denser than any of those substances ... slightly more so than lead, somewhat more so than copper, and a lot more so than aluminium.
It is not true; osmium is more dense.
Mercury is an element and therefore a pure substance.
FALSE. There are probably 15 elements more dense than mercury. A few examples would be Osmium, Platinum, and Gold, just to name a few.
The densest liquid substance is mercury. It has a high density compared to other liquids, which makes it commonly used in barometers and thermometers.
With a density of 8,96 g/cm3 copper can be considered a dense metal.
Pressure caused by the more dense (water) substance surrounding the gloved hand.
ANSWER:From least dense to most dense, Water, Aluminum, Zinc, Iron, Copper, Silver, Lead, Mercury, Gold. See the related link for more information.BY: Justin Chance :)

Copper does not sink in water.. An object with higher density than water sinks while an object with lower density than water floats..
mercury
no beacause a rubber duck floats and if an object floats in water, is is less dense than the water if it sinks it is more dense
