type 'air' in wikipedia and there you will see that the concetration of hydrogen in air is: 0.55 ppmv (parts per milion, volumic; so there is ~half a liter of hydrogen in one million liters of air)
No, hydrogen makes up about 0.00005% of the Earth's atmosphere. The majority of the air we breathe is nitrogen (about 78%) and oxygen (about 21%).
The percentage of hydrogen on earth is just 0.25%
The exosphere is the outermost layer of Earth's atmosphere, where air is extremely thin. It contains a very small percentage of the total mass of the atmosphere, with most of the air present in the lower layers. The exosphere consists mainly of hydrogen and helium atoms.
NO. Hydrogen gas is non-toxic. However, it can displace oxygen (and if hot enough burn in it) and thus can be an asphynxant in large quantities. But hydrogen by it self is not toxic at all.
this happens because hydrogen is lighter than air
No.

Hydrogen is in atmosphere.We get it from air.
yes hydrogen is found in the human body sine the body is 75 percent water and water is 66 percent hydrogen so yes you have hydrogen in your body
In terms of the number of atoms it is 50%. In terms of mass, it is 5.88%.
Yes, hydrogen and air can mix. However, hydrogen is highly flammable and when mixed with air in certain concentrations, it can form an explosive mixture. This is why caution is needed when handling and storing hydrogen in the presence of air.
The difference between 6%, 9%, and 12% Hydrogen Peroxide solution is the Hydrogen content.
Water
Yes Saturn has air but it is not breathable air. So if you go to Saturn and yo are not wearing proper air-gear then you will die because of the air. No it is not cautionous air but you will die.
The hydrogen peroxide sold in drugstores contains three percent hydrogen peroxide and 97 percent water.
