Hydrogen is a colorless, odorless gas. It is the simplest element in nature, having one proton in the nucleus and one electron in the shell.
Hydrogen is extremely light, and can be used to fill balloons. Hydrogen is HIGHLY flammable. When hydrogen burns, the result is water.

2. Non-poisonous.
3. Its vapour density is 1. (Vapour density of air = 14.4). Thus it is much lighter than air. Passing hydrogen through soap solution can easily prove this. The bubbles formed will rise into the air.
4. Solubility of H2 is very low. Only 2 volumes of hydrogen dissolve per 100 volumes of water under ordinary conditions.
5. Hydrogen can undergo liquefaction. Cooling hydrogen to below -240oC, under a pressure of 20 atmospheres or more, can liquefy it. Liquid hydrogen is a colourless liquid, which boils at -253oC. It solidifies when allowed to evaporate, because, during the process, intense cooling takes place. Solid hydrogen is a transparent ice like crystalline substance with melts at -259. 4oC.

Who created hydrogen?
how made hydrogen how made hydrogen how made hydrogen how made hydrogen
What does h stand for in h20?
Hydrogen. The lightest element.
What is difference between hydrogen sulfide and hydrogen sulphide?
H2 is molecular hydrogen. H2S is hydrogen sulfide and is extremely toxic.
Is hydrogen poisonous?
Hydrogen is not poisonous.
Who has the stronger dipole-dipole hydrogen chloride or hydrogen flouride?
Hydrogen fluoride as it is a hydrogen bond.
Is a H2 or hydrogen gas?
Hydrogen is a gas. H2 is the description of its molecular structure (2 hydrogen atoms bound together).
What is a brief description of hydrogen?
the simplest element. Hydrogen is a gas, a non-metal, it is the lightest element.
What is a short simple description of hydrogen economy?
It is an alkali metal
A description for the formula H2O is two?
No. You might say a description for the formula H2O is two hydrogen atoms bonded to an oxygen atom.
What is the description for the formula H2O?
2 atoms of hydrogen and one atom of oxygen.
What does the h stand for in pH scale?
The letter h in pH scale stands for Hydrogen. The proper description for the name ph. is potential of Hydrogen.
Which statement best describes the molecules made of carbon hydrogen?
Molecules made of carbon and hydrogen are various and diffuse. The best description is that they are hydrocarbons and they burn well.
Description of hydrogen-?
Brief description: hydrogen is the lightest element. It is by far the most abundant element in the universe and makes up about about 90% of the universe by weight. Hydrogen as water (H2O) is absolutely essential to life and it is present in all organic compounds. Hydrogen is the lightest gas. Hydrogen gas was used in lighter-than-air balloons for transport but is far too dangerous because of the fire risk (Hindenburg). It burns in air to form only water as waste product and if hydrogen could be made on sufficient scale from other than fossil fuels then there might be a possibility of a hydrogen economy.
Description of an oxidation reaction that occurs during cellular resperation?
Glucose lose electrons and hydrogen to form Carbon dioxide.
What is the description Of Saturn's surface?
The planet Saturn does not have a solid surface. Saturn is almost entirely made up of gases, hydrogen and helium.
What is the building component that is made up of carbon hydrogen oxygen nitrogen and sometimes sulfur?
Sounds like a description of amino acids.
What is a molecule composed almost entirely of hydrogen and carbon?
That's a reasonable description of a "hydrocarbon"
