Hydrogen gas has a very low density; 0,08988 g/L; uranium hexafluoride (as gas) is very dense, between gases.

The density of hydrogen is lower than air and can be used to fill balloonswhy is helium used instead of hydrogen?
Hydrogen is flammable and explosive.
Why do substances with higher density have a higher boling and freezing point?
Um... who says they do? Lead has a significantly higher density than aluminum but a considerably lower melting point.
How much hydrogen does it take to drive a car?
It depends how far you want to go, how fast, and how big your car is! But when you ask a vague question you get a vague answer... a lot. The energy density of hydrogen is much lower than gasoline, even when it is highly compressed.
What is the definition of lower density when solid?
A definition of lower density doesn't exist. Solids with densities under 1,00 g/cm3have a very low density.
Why do your pickled eggs float?
The density is lower than the density of water.
How do you lower the density of the hydrogen gas?
You can lower the density of hydrogen (or any) gas by heating it in a container where it is free to expand, like a balloon.
What element has the lower density of all of the elements?
hydrogen
Does hydrogen have a low density?
Yes, hydrogen can be considered to have a low density. In fact, it is the least dense of all the elements.
The density of hydrogen is lower than air and can be used to fill balloonswhy is helium used instead of hydrogen?
Hydrogen is flammable and explosive.
Which of these describes a benefit of nuclear fusion?
Hydrogen is more available than uranium-235.
What are physical properties give examples?
Physical we mean only the structure, state, lustre if any, density etc. Example: Hydrogen gas is lighter than oxygen because of its lower density
What elements are in coal?
it is a fossil fuel-the elements in coal are mainly hydrogen and carbon, with lower levels of hydrogen, oxygen, sulfur and nitrogen, yet some trace elements within coal are radioactive. These include Uranium, Thorium, Radon and Radium.
Why is density of hydrogen lower than air and can be used to fill balloons why is helium used instead oh hydogen?
Because helium is lighter
Why do substances with higher density have a higher boling and freezing point?
Um... who says they do? Lead has a significantly higher density than aluminum but a considerably lower melting point.
Does oil or water have a lower density?
Oil floats on water, and has a lower density.
How does the neutron bomb work?
A neutron bomb is a type of hydrogen bomb. It actually was a development that came from the late 1950s work by the US to make "clean hydrogen bombs" that produced very little fallout. In a conventional hydrogen bomb the tamper (device to contain the nuclear reaction as long as possible to get as much energy from it as possible) is usually made with depleted uranium because of its high density and low cost. While depleted uranium will not support a neutron chain reaction it will fission when hit by the high energy neutrons produced by the fusion reaction of the hydrogen bomb. This depleted uranium fast fission can produce up to 90% of the total yield in some hydrogen bomb designs, as well as a proportional amount of the fallout. In a "clean hydrogen bomb" the tamper is instead made of some other very dense metal that unlike uranium will not fission when hit by high energy neutrons. Lead and tungsten have been used. However the explosive yield of a "clean hydrogen bomb" will be lower than a similar conventional hydrogen bomb because there is no fission in the tamper. But as these materials do not consume the high energy neutrons, they escape from "clean hydrogen bombs". It was observed that these neutrons easily pass through tank armor and building walls, killing those inside while the lower yield produces less blast and fire damage. Thus was born the idea of the neutron bomb.
What are the positive enriched uranium?
- the energy released from enriched uranium is higher compared to natural uranium- the amount of uranium needed for a reactor is lower- research reactors work only with enriched uranium- atomic bombs have highly enriched uranium or plutonium
