What percent of human body is hydrogen?
9.5 percentBy mass, about 96 percent of our bodies are made of four key elements: oxygen (65 percent), carbon (18.5 percent), hydrogen (9.5 percent) and nitrogen (3.3 percent).
These elements do not give color to fireworks, but they are found in our body’s most abundant and important molecules, including water, proteins and DNA..
What is interesting about hydrogen?
Hydrogen is the very first element on the periodic table, and it is the most common element in the universe, making up about 75% of its mass. Hydrogen is extremely flammable, meaning it catches fire easily. It is a colorless, odorless, and tasteless gas.
What are 5 hydrogen properties?
At standard temperature and pressure, hydrogen is a nontoxic, nonmetallic, odorless, tasteless, colorless, and highly combustible diatomic gas with the molecular formula H2.
What is the Colour of hydrogen?
Hydrogen is a colourless gas – depending on the production type, different colours are assigned to the hydrogen. Green hydrogen is produced by electrolysis of water, using only electricity from renewable energies.
How dangerous is hydrogen?
When liquid hydrogen is stored in tanks, it’s relatively safe, but if it escapes there are associated hazards. Topping the list of concerns is hydrogen burns. In the presence of an oxidizer — oxygen is a good one — hydrogen can catch fire, sometimes explosively, and it burns more easily than gasoline does.
What are 3 interesting facts about nitrogen?
Facts:N has no odor, is tasteless, and colorless.Nitrogen gas (N2) makes up 78.1% of the Earth’s atmosphere.Atmosphere contains an estimated 4,000 trillion tons of N. … Nitrogen is not a metal.Nitrogen gas is inert. … French chemist Antoine Laurent Lavoisier named nitrogen azote, meaning without life.More items…
Is silicon a metal?
Silicon the semiconductor It’s usually found linked up with a pair of oxygen molecules as silicon dioxide, otherwise known as silica. Quartz, an abundant ingredient in sand, is made up of non-crystallized silica. … Silicon is neither metal nor non-metal; it’s a metalloid, an element that falls somewhere between the two.
Does the human body use hydrogen?
The most important function of hydrogen in the human body is to keep you hydrated. Water is made up of hydrogen and oxygen and is absorbed by the cells of the body. Therefore, it is a crucial element which is used not in our body but also as a fuel, in military weapons etc.
How much hydrogen is in the human body?

Where do we find hydrogen?
Hydrogen is easily the most abundant element in the universe. It is found in the sun and most of the stars, and the planet Jupiter is composed mostly of hydrogen. On Earth, hydrogen is found in the greatest quantities as water.
Will we ever run out of hydrogen?
What will happen when the sun dies? But in about 5 billion years, the sun will run out of hydrogen. Our star is currently in the most stable phase of its life cycle and has been since the birth of our solar system, about 4.5 billion years ago.
What makes hydrogen unique or special?
Hydrogen is unique in that it can act like a metal in an ionic compound, donating electrons to the non-metal it bonds with or like a non-metal in a molecular compound, sharing electrons with another atom.
Why is hydrogen so important?
The hydrogen atom has one proton and one electron. The most abundant element in the universe, hydrogen is also a promising source of “clean” fuel on Earth. … Hydrogen is essential for life, and it is present in nearly all the molecules in living things, according to the Royal Society of Chemistry.
Why is hydrogen special in the periodic table?
Hydrogen is a nonmetal and is placed above group in the periodic table because it has ns1 electron configuration like the alkali metals. … Because hydrogen is a nonmetal and forms H- (hydride anions), it is sometimes placed above the halogens in the periodic table. Hydrogen also forms H2 dihydrogen like halogens.
Can you breathe hydrogen?
Inhaled hydrogen gas (H2) has been shown to have significant protective effects on ischemic organs. Clinical trials abroad have shown promise that treatment of patients suffering from stroke, cardiac arrest, or heart attacks may benefit from inhaling hydrogen gas during the early recovery period.
Is HHO gas safe to breathe?
Inhalation risk: On loss of containment, a harmful concentration of this gas in the air will be reached very quickly. Physical dangers: The gas mixes well with air, explosive mixtures are easily formed. … High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
What 2 groups can hydrogen act like?
Hydrogen, like the halogens, has one electron short of a complete outer shell and can form H- ions like Cl- and therefore forms ionic compounds with reactive metals – NaH similar in structure to NaCl. Hydrogen also exists as a diatomic gas like fluorine and chlorine.
Is hydrogen a special element?
Hydrogen is the most abundant element in the universe, comprising 75% of the universe by mass. … Hydrogen is special among the elements for the reason it can easily form compounds in either the +1 or -1 oxidation states, where it can act essentially like a metal or a non-metal, depending on the circumstances.
What are 3 interesting facts about hydrogen?
Interesting Facts about HydrogenScientists estimate that Hydrogen makes up over 90 percent of all the atoms in the universe.It is the only element that can exist without neutrons.Hydrogen becomes a liquid at very low temperature and high pressure. … Around 10 percent of the mass of the human body is hydrogen.More items…
Can hydrogen kill you?
Swallowing food-grade hydrogen peroxide can make you severely ill, or cause death to occur. Industrial strength (90 percent). Swallowing even tiny amounts of hydrogen peroxide at this strength can be fatal. It is toxic to drink, touch, or breathe.
What is the main use of hydrogen?
Nearly all of the hydrogen consumed in the United States is used by industry for refining petroleum, treating metals, producing fertilizer, and processing foods. U.S. petroleum refineries use hydrogen to lower the sulfur content of fuels.
