Hydrogen is the most common element found on Earth. It is extremely important to humans as water is made up of two parts hydrogen (and one part oxygen).
It is also the simplest and lightest element of them all. But did you know hydrogen can be outside of Earth in large gas giant planets and stars?
Or that it is present in almost all the molecules of living things?
Let’s explore the world of hydrogen to see what other gassy facts we can uncover.
Hydrogen Facts for Kids
- The only element without neutrons.
- Metallic hydrogen may exist in the cores of gas giant planets like Jupiter.
- Hydrogen makes up 10 percent of the human body.
- Due to its highly flammable nature, it is dangerous.
- Using a dilute acid and a metal, you can create hydrogen gas in the lab.
- The combination of liquid hydrogen and liquid oxygen can also be used as rocket fuel
- On the periodic table, hydrogen is the first element.
- The French chemist Antoine Lavoisier gave hydrogen its name.
- At low temperatures and high pressure, hydrogen becomes a liquid. At very high pressure, hydrogen becomes a liquid metal.
Sunlight is created by hydrogen elements in the Sun.
Hydrogen provides most of the energy on Planet Earth. Helium is formed when hydrogen atoms undergo extreme pressure.
A hydrogen fuel cell can generate electricity by reacting hydrogen with oxygen.
In order to make hydrogen fuel cells more economical and practical, scientists are working on the way to do this.
Liquid hydrogen is a form of hydrogen that can be obtained by cooling hydrogen below its critical point of 33 K or by cooling it to 20.28 K (252.87 °C; 423.17 °F).
Liquid hydrogen can be stored in pressure and thermally insulated containers.
The earliest recordings of hydrogen date back to 1520. A Swedish Alchemist by the name of, Philippus Aureolus Paracelsus, noted that gas was being given off when iron was dissolved in sulfuric acid.
Fast forward to the year 1766. Henry Cavendish was experimenting with the reaction of acids on certain metals and discovered a gas coming from them, as well. This was indeed hydrogen, but it took until 1783 before it would get its official name and the recognition it deserved.
Where is Hydrogen Found?
Since hydrogen bonds with other elements, it can be found in water, natural gas, and methanol. In order to produce hydrogen, it first must be “unlocked” or freed from the other molecules. Scientists have learned how to do this process. They can “harvest” hydrogen from the electrolysis of water or by heating natural gas with steam. This technology makes hydrogen widely available to everyone on the planet.
What is Hydrogen Used For?
You may be surprised to learn all the uses of this important element. Check out the things Hydrogen is used for;
- NASA uses hydrogen as rocket fuel.
- It was used to power hot air balloons.
- It is used in fertilizer.
- It’s added to fats and oils.
- It is used in welding.
- It can be made into hydrogen peroxide, which is used in cleaning products.
- It’s used in the making of flat glass sheets.
- In the making of sugar
The Not-So-Nice Side of Hydrogen
Although, for the most part, hydrogen is relatively safe, it does have a not-so-nice side. It can be highly toxic when breathed in large doses. It can cause a person to pass out or even die.
Hydrogen is also highly flammable and causes fires or even explosions. It’s always best to handle hydrogen carefully to avoid any of these potential dangers.
Fun Facts About Hydrogen
- Hydrogen is 14 times lighter than air?
- Around 3 billion cubic feet of hydrogen is produced each year in the United States alone?
- Gas giants like Jupiter are made primarily of hydrogen?
- Hydrogen is a clean fuel? When it burns, it only produces water.
- If you were to liquefy hydrogen, could it give you severe frostbite?
Try This ~ A Fun Experiment With Hydrogen
It’s always fun to see chemicals at work, so try this easy experiment to see how hydrogen can make mammoth foam.
You Will Need:
- 1 big pan
- 1 empty soda bottle
- ½ cup hydrogen peroxide (6 percent)
- 5 drops of food coloring
- 1 squirt of dish liquid
- 2 tablespoons of warm water
- 1 teaspoon of yeast
First, combine the hydrogen peroxide, food coloring, and dish liquid into a soda bottle. Now in a separate dish, mix the yeast and warm water.
Give it a swirl for about 1 minute. Now with your bottle in the middle of the pan, pour the yeast mixture into the soda bottle Watch what happens…Don’t worry, it’s not toxic!
You should see giant foam bubbles up and over the sides of the bottle. You may even notice the bottle feels slightly warm.
This is called, an exothermic reaction, and it happens when energy is released as heat. Now that you have learned all about hydrogen and how important it is, go out and impress your friends and family with these fun facts.
They may just believe you are a hydrogen-smarty-pants with your knowledge of these fascinating factoids.
