Aerogel, i think.
It may be hydrogen.

∙ 13y agoThere's something of a debate, but the general consensus is that osmium is just a little bit denser than iridium. Osmium is around 22.61g/cm3 (grams per cubic centimetre,) but Iridium is around 22.56g/cm3. The two have switched places for first and second in the leader-board of densest metals several times over the years.
Either Osmium or Iridium.

∙ 14y agoFor elements:
Osmium and Iridium both have densities of over 22 g/cm3. It's very nearly a tie which of the two is denser.
For minerals:
The mineral Chengdeite (Ir3Fe) has a Specific Gravity is 19.3 g/cm3

How does an object's density determine whether the object will sink or float in water?
the simple rule is that if your density is higher than the substance it will sink and if it is lower it will float density= mass divided by volume. Example:Mass 7.5g Volume:2cm3 so 7.5 Divided by 2= 3.75g/cm3 that is your density of object
What is the word meaning how soft or hard an object is?
dense or density
What is dence?
Dense means how much water and object will take up when placed in water.
If an object has a volume of 50 Cm3 and a mass of 956G what is the density of the object?
It is 100 g/cm3 which is way above the most dense element!
An object floats because it displaces a weight of fluid?
An object floats for three reasons. One, it is less dense than the solution it is floating in. Such as a piece of wood. Two, the object contains something that is less dense than what it is floating in. Such as a baloon. Three, the shape of the object is such that it does not have enough weight to displace enough of the solution to envelop the object. Such as with any seagoing vessell.
Where does most of our knowledge about the earth come from?
Name the layers of earth in order from most dense to least dense
Where does most of our knowledge about earth come from?
Name the layers of earth in order from most dense to least dense
Is the core the least dense layer of the earth?
No. It is the most dense.
Which of earth's atmosphere layers is the most dense?
The troposphere is the most dense since it is closest to the surface of the earth and has the highest pressure.
What is the most dense region of the earth called?
The Inner Core is the most dense part of the Earth. It is a solid core of iron and nickel.
Is Earth the least dense of all planets?
No. In fact it is the most dense planet. The least dense is Saturn.
What is the most dense planet?
Mercury has a density of 5.427 g/cm³ Earth has a density of 5.515 g/cm3 So Earth is the most dense planet. [See discussion for more information] NB: Mercury is the most dense planet in our solar system when not accounting for gravitational compression.
What is the most dense subtance on earth?
Osmium
Is the earth dense than the sun?
Overall yes, much of the sun's volume is gaseous material which is much lighter than the rock and metal that the earth is composed of. The density of Earth is 5.56 g/cm3 whereas the sun is 1.4 g/cm3 the earth is the most dense object in our Solar System (as far as we know)
Is the inner core the least dense layer of the earth?
The core is the most dense layer
Which atmospheric layer is dense?
The troposphere is the closest to the Earth and most dense atmospheric layer
What is more dense a cold object or a hot object?
A cold object is more dense.
