Q. What are the two simplest elements in the universe?
Universe Elements This means the most common elements in the universe are hydrogen and helium. These two elements comprise around 98% of all the elements in the universe, with hydrogen at 75% and helium at 23%. Hydrogen is the simplest element that exists because it only has one proton and one electron.
Q. Why is hydrogen the simplest element in the universe?
Why is hydrogen the most abundant element in the universe? Hydrogen has one proton, one electron and is the only element with no neutrons, making it the simplest element in the universe. Because of this, Hydrogen is believed to be the most abundant element, accounting for about 90% of the visible universe.

Q. What is the first element in the universe?
hydrogen
Q. What is the least common element in the universe?
- The least abundant naturally occurring element in the universe is Astatine – Wikipedia .
- To this date, Astatine has never been found in nature.
- Naturally occurring Astatine is formed when Francium, the second least abundant element, decays.
Q. What is the rarest element in nature?
element astatine
Q. Are there any elements only found in space?
Technetium was made in the laboratory back in the 1930s, but was first discovered in these giant stars in 1952, the only naturally occurring place in the Universe where it’s been discovered in any sort of large abundance.
Q. Can you hear sound in space?
Space is a vacuum — so it generally doesn’t carry sound waves like air does here on Earth (though some sounds do exist in outer space, we just can’t hear them).
Q. Can an explosion be heard in space?
To travel to us from outer space, the wave must be able to travel through regions of space which are essentially vacuum (nothing there). Sound cannot do this, as it requires a medium to propagate in, so we would not be able to hear the explosion.
Q. Does space sound like underwater?
The common explanation for this is that space is a vacuum and so there’s no medium for sound to travel through. But that isn’t exactly right. Space is never completely empty – there are a few particles and sound waves floating around.
Q. Can you hear on Mars?
Perseverance’s Microphones Given that sound waves need an atmospheric medium through which to travel, many people are surprised to learn that any sounds at all can be heard on Mars. The atmospheric pressure on the Red Planet’s surface is small, amounting to less than 1% of Earth’s sea level pressure.
