What element makes most of the universe?
hydrogen
The most abundant element in the universe is hydrogen, which makes up about three-quarters of all matter! Helium makes up most of the remaining 25%.
What element makes 90% of the universe?
Hydrogen
Hydrogen;H; The element hydrogen makes up most of the universe and powers our stars but it is rare on Earth and must be made from fossil fuels.

Is hydrogen the most abundant element in the universe?
Hydrogen is the most abundant element in the universe, accounting for about 75 percent of its normal matter, and was created in the Big Bang. Helium is an element, usually in the form of a gas, that consists of a nucleus of two protons and two neutrons surrounded by two electrons.
What are the 5 elements of the universe?
According to the five elements theory, everything in nature is made up of five elements: Earth, Water, Fire, Air, and Space.
Is carbon abundant in the universe?
On a weight basis, carbon is 19th in order of elemental abundance in Earth’s crust, and there are estimated to be 3.5 times as many carbon atoms as silicon atoms in the universe. Only hydrogen, helium, oxygen, neon, and nitrogen are atomically more abundant in the cosmos than carbon.
Is oxygen abundant in the universe?
Oxygen is the third most abundant element in the universe after hydrogen and helium (by mass) and it’s the most abundant element (by mass) in the Earth’s crust, making up almost half of the crust’s mass.
What percentage of the universe is hydrogen?
Approximately 73% of the mass of the visible universe is in the form of hydrogen. Helium makes up about 25% of the mass, and everything else represents only 2%.
Which 2 elements are most abundant in the visible universe?
The Most Abundant Element in the Universe
- Hydrogen is a gas that makes up around 75% of the visible universe.
- Helium is another gas in stars.
- Oxygen is the third most abundant gas in the universe.
- Carbon is found in the stars, comets, and atmospheres of most planets.
What the four most common elements in the universe?
Oxygen.
What are the two most plentiful elements in the universe?
Nitrogen – 78%
What two elements is the universe made primarily of?
You see, the Universe starts off with hydrogen and helium, all stars produce helium, and then stars over a certain mass threshold produce carbon, nitrogen, oxygen and lots of heavier elements. But carbon was already element #6; what about lithium, beryllium and boron (elements #3, #4 and #5)?
How do we know what elements are in the universe?
How do we know what elements make up the universe. – The elements that make e universe are the ones we find on earth. – We have discovered or synthesized almost all elements, only possibility is finding the ones on the island of stability. – Apart from those few, we know exactly what elements make up the universe.
