Hydrogen has a relative density of 0.090 grams/liter (g/L) at 0°C (32°F) and regular atmospheric pressure.
Except that's the density of the gas, quite a different proposition to the density of an individual atom. And the atom itself is mostly space, with a stupendously high density nucleus.

What gas is the most or least dense when heated?
When heated, gases typically expand and become less dense. So, a gas would be least dense when heated.
Is helium dense or less dense than water?
While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water. While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water.
What are some of the least dense materials?
Pentane is 0.626 g/cm^3 at 25 C and one atmosphere. Hydrogen is 0.070 g/cm^3 at -253 C and one atmosphere.Read more: What_is_the_lowest_density_liquid_commonly_availablei did not wright this!

Does hydrogen fusion occur in the corona?
Hydrogen fusion does not occur in the corona of the sun. Fusion reactions occur in the sun's core where conditions are hot and dense enough for hydrogen nuclei to combine to form helium, releasing energy in the process. The corona is cooler and less dense than the core, so fusion cannot take place there.
Does Jupiter have a dense core of hydrogen and helium?
No, it has a dense rocky core in the middle!!
Why hydrogen gas collected by upward delivery?
Because hydrogen gas is less dense than air(mostly nitrogen and oxygen), and the less dense gas flows to go above the more dense(and escape the atmosphere).
Does hydrogen float in water?
if it is less dense than the water, it floats. Water can have different density.
What gas is the most or least dense when heated?
When heated, gases typically expand and become less dense. So, a gas would be least dense when heated.
Why is hydrogen less dense than water?
At standard temperature and pressure (STP) hydrogen is a gas and water is a liquid.
Is ice cube a solid gas or liquid?
solid with hydrogen bonds making it less dense than its liquid form
Ice is less dense than water because of which type of bond?
Ice is less dense than water due to hydrogen bonding. When water molecules freeze into ice, the hydrogen bonds hold the molecules in a more spaced-out, lattice-like structure, causing ice to be less dense than liquid water.
What is the least dense thing?
Hydrogen gas is considered the least dense element. It is less dense than air, which is why it is often used in balloons.
Is helium dense or less dense than water?
While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water. While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water.
Why does hydrogen take on the properties of a metal in the planet Jupiter but not on the planet Earth?
Deep inside Jupiter hydrogen is in a very dense condition due to extreme pressure. This dense condition is called "metallic hydrogen" because then it can conduct electricity. On Earth the pressure is simply not strong enough to produce metallic hydrogen.
What element has the lowest density of all of the elements?
The element which has been measured to have the lowest density is hydrogen. Not only is hydrogen the least dense element, it is also the most plentiful on earth.
Is cotton least dense?
'Least' is a comparison word. Compared to iron and lead yes cotton is least dense. Compares to oxygen gas and hydrogen gas, no it is not least dense.
