Have you ever thought about what happens when you drink water? You’re actually consuming the most common element in the universe: hydrogen. Let’s dive into the fascinating world of hydrogen and see why it’s so important!
Hydrogen is the simplest element you can find. It has just one proton in its nucleus, which makes it unique and places it at the top of the periodic table. It’s also the most plentiful element in the universe, with helium coming in second. Right after the Big Bang, the universe was mostly made up of hydrogen and helium atoms.
As the universe cooled down, hydrogen atoms began to form gas clouds. These clouds eventually clumped together to create protostars. As these protostars grew, they gained enough gravity to pull in more material. This increased their mass, pressure, and heat, causing hydrogen atoms to fuse into helium. This fusion process is what makes stars shine brightly.
Inside stars, even heavier elements are formed. When stars explode, they scatter these elements across the universe. These materials eventually become part of new stars and planets, including Earth.
Even though hydrogen is the most abundant element in the universe, it’s not as common on Earth. The name “hydrogen” comes from Greek words meaning “water-forming,” because it’s a key part of water (H2O). Our bodies are made up of a lot of water, but hydrogen makes up less than 10% of the human body and less than 0.15% of the Earth’s material.
On Earth, oxygen and nitrogen are more common in the atmosphere, and silicates make up most of the Earth’s crust. Hydrogen is mainly found in compounds like water. It doesn’t stay in the atmosphere for long because Earth’s gravity can’t hold onto it.
Hydrogen is incredibly useful. It’s used in rocket fuel, welding, making hydrochloric acid, and in reducing metallic ores. As a fuel, hydrogen is clean because it doesn’t produce carbon emissions. When it burns, it only creates water as a byproduct.
There’s also potential to get hydrogen from space. Some companies are exploring mining asteroids for hydrogen to use as fuel, which could help with space exploration and even power vehicles on Earth.
Hydrogen is a fascinating element with many uses and a bright future as a clean energy source. What do you think about using hydrogen as a fuel? Is it worth exploring the universe for more? Share your thoughts with others and keep learning about this amazing element!
Create a 3D model of a hydrogen atom using craft materials like styrofoam balls, toothpicks, and paint. This will help you visualize its simple structure with one proton and one electron. Present your model to the class and explain why hydrogen is unique.
Participate in a simulation activity where you act out the process of star formation. Use props to represent hydrogen gas clouds, gravity, and fusion. This will help you understand how stars are born and how hydrogen plays a crucial role in this process.
Research and create a poster that shows the various uses of hydrogen in everyday life, such as in fuel cells, industrial processes, and space exploration. Share your findings with the class to highlight the importance of hydrogen in modern technology.
Conduct a simple electrolysis experiment to split water into hydrogen and oxygen gases. Use a battery, water, and electrodes to observe the process. This hands-on activity will demonstrate how hydrogen can be extracted from water.
Engage in a class debate about the potential of hydrogen as a future fuel source. Discuss its benefits and challenges, such as environmental impact and feasibility. This will encourage critical thinking and help you form an informed opinion on hydrogen’s role in energy.

When you drink water, you’re consuming the most abundant element in the universe. But what’s really going on with hydrogen? Hi everyone, Amy here for DNews. You might not think about it in scientific terms, but you consume a lot of hydrogen, and you’re even made of hydrogen! This is not as strange as it sounds; you’re not unknowingly a cyborg or anything.
Hydrogen is the simplest element, consisting of just one proton orbiting its nucleus. This simple structure allows it to hold the top spot on the periodic table of elements. It’s also the most abundant element in the universe, with helium coming in a distant second. When the universe was just a fraction of a second old, immediately after the Big Bang, it was about 92% hydrogen atoms and 8% helium atoms by number, which is roughly three-quarters hydrogen by mass, with trace amounts of other elements.
As the universe cooled, these early atoms stabilized and formed gas clouds that eventually clumped together to create protostars. These protostars grew massive enough to develop their own gravity, drawing in other material, adding mass, pressure, and heat until hydrogen atoms fused together to form helium. This fusion reaction made stars bright. Heavier elements are also formed inside stars, and when stars die and explode, they send those heavier materials throughout the universe, where they are eventually incorporated into new stars and protoplanets, including our Earth.
So, all those elements found in stars are also present on our planet, but not in the same amounts. Hydrogen may be the most abundant element in the universe, but it’s relatively rare on Earth. The name hydrogen comes from the Greek words for “water” and “forming,” linking its existence to water, as it is the H in H2O. Although the cells that make up our body contain a high amount of water, hydrogen constitutes less than 10% of the material in the carbon-based human body and less than 0.15% of the material that makes up the Earth.
Our planet is rich in oxygen and nitrogen, which are the most abundant elements in our atmosphere, as well as silicates, which make up the bulk of the crust. Hydrogen is primarily found in compounds like water, and the hydrogen that does reach the Earth doesn’t stick around; it escapes quickly from the atmosphere because the Earth’s gravity can’t hold onto it.
However, hydrogen is immensely useful. It is used in rocket fuel, welding, the production of hydrochloric acid, and reducing metallic ores. As a fuel, it’s a clean energy source. Hydrogen carries energy without carbon, so when it burns, it produces water as a byproduct.
There’s also potential to obtain hydrogen from other sources, such as off the planet. Companies like Planetary Resources are exploring the idea of mining asteroids not for precious metals, but for elements like hydrogen that could be used to create fuel, supporting space exploration and potentially vehicles on Earth as well.
