275 examples of Hydrogen in a sentence

It takes CO2 to methane using molecular hydrogen as its energy source.
The particles fuse together, and the Sun turns hydrogen into helium through quantum tunneling.
The two white balls in the middle are protons, and you can see that it's a double hydrogen bond.
First of all, an atom of eka-aluminum has an atomic weight of 68, about 68 times heavier than a hydrogen atom.
As food travels through our digestive tract, it reaches the fermentors who extract energy from these sugars by converting them into chemicals, like alcohol and hydrogen gas, which they spew out as waste products.
Centuries of scientific thought and experimentation have established that the real elements, things like hydrogen, carbon, and iron, can be broken down into atoms.
In Leucippus's theory, the atom is the smallest, indivisible bit of stuff that's still recognizable as hydrogen, carbon, or iron.
But just three days later, on a day they called Red Monday, the media and the politicians told us, and we believed, that Sputnik was proof that our enemy had beaten us in science and technology, and that they could now attack us with hydrogen bombs, using their Sputnik rocket as an IBM missile.
Hydrogen has one proton, helium, two protons, lithium, three protons, and so on.
Meanwhile, the human body consists of 65% oxygen, 18% carbon, 10% hydrogen, and 7% of various other elements including 0.002% of silicon.
Hydrogen is hydrogen because it has just one proton, carbon is carbon because it has six, gold is gold because it has 79, and so on.
It was about 75 percent hydrogen and almost all the rest was helium.
Hydrogen atoms smash together to form helium, accompanied by a great release of energy, strong enough to counteract the shrinking force of the gravity.
Gas clouds, now containing many elements besides the original hydrogen and helium, have higher density areas that attract more matter, and so on.
It's still mostly hydrogen at 71 percent, with most of the rest being helium at 27 percent.
But bear in mind that while the first stars were made up of hydrogen and helium alone, the remaining elements in the periodic table make up two percent of the sun.
Small planets like ours don't have enough gravity to hold on to much hydrogen or helium gas since both of those are very light.
Think about this: with the exception of hydrogen and some helium, the ground you walk on, the air you breath, you, everything is made of atoms that were created inside stars.
In the second step in the process, we add a small amount of hydrogen peroxide and shine ultraviolet light on the water.
The ultraviolet light cleaves the hydrogen peroxide into two parts that are called hydroxyl radicals, and these hydroxyl radicals are very potent forms of oxygen that break down most organic chemicals.
Well, both are carbohydrates with the same chemical composition of carbon, hydrogen, and oxygen.
But suppose we explore a question about the physics of atoms, like what does the motion of an electron around the nucleus of a hydrogen atom look like?
The same sort of thing happens to physical systems at quantum scales, like an electron orbiting in a hydrogen atom.
Some of the foul-smelling byproducts of these reactions, such as hydrogen sulfide and cadaverine, escape into the air and waft their way towards unsuspecting noses.
Stars are mostly made up of hydrogen, the simplest and lightest element.
This process releases energy from the hydrogen, making the star shine.
Over many millions of years, fusion transforms hydrogen into heavier elements: helium, carbon, and oxygen, burning subsequent elements faster and faster to reach iron and nickel.
In extreme contrast to the million year transformation of hydrogen to helium, the creation of the heaviest elements in a supernova takes place in only seconds.
These green pigments were made from a compound called cupric hydrogen arsenic.
So, imagine that the building blocks are little atoms and there is a hydrogen here, a carbon here, a nitrogen here.
