Oxygen is the third most abundant element in the Universe today, and in the very, very far future, may even have the opportunity to rise further as hydrogen (and then possibly helium) falls from its perch.
What are the 4 most abundant elements in the universe?
- 1.) Hydrogen. Created during the hot Big Bang but depleted by stellar fusion, ~70% of the Universe remains hydrogen.
- 2.) Helium. About 28% is helium, with 25% formed in the Big Bang and 3% from stellar fusion.
- 3.) Oxygen.
- 4.) Carbon.
- 5.) Neon.
- 6.) Nitrogen.
- 7.) Magnesium.
- 8.) Silicon.
What are the three most abundant elements in the universe?
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%. Oxygen is the third-most abundant element in the universe.
What element makes 90% of the universe?
In the universe as a whole, the most common element is hydrogen (about 90% of atoms), followed by helium (most of the remaining 10%).

What is the 4th most abundant element?
Carbon is the fourth most abundant element in the universe. The first being hydrogen, followed by helium and oxygen.
Is oxygen the third most abundant element?
After hydrogen and helium, oxygen is the third most abundant chemical element in the known universe. It is the second most abundant element in the Earth’s geosphere after iron and the most abundant element by mass in the Earth’s crust — at about 47% to 49%.
What element is the key to life?
Oxygen is the pivot, which produces water and air and it is indispensable to the life. Hydrogen participates with oxygen to produce water, without which life would not be possible.
What is the 2nd most abundant element in the universe?
Helium is the second-most abundant element in the universe, after hydrogen, and accounts for about 25 percent of the atoms in the universe. Most of the helium in the universe was created in the Big Bang, but it also is the product of hydrogen fusion in stars.
What is the least common element on Earth?
Astatine is the rarest element on Earth; only approximately 25 grams occur naturally on the planet at any given time. Its existence was predicted in the 1800s, but was finally discovered about 70 years later.
What is the heaviest element?
There are 91 naturally occurring elements (but it depends on how you count them). The heaviest element that occurs in large quantity is uranium (atomic number 92).

Who discovered Earth?
The first person to determine the size of Earth was Eratosthenes of Cyrene, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations. Eratosthenes was born around 276 B.C., which is now Shahhat, Libya. He studied in Athens at the Lyceum.
What is Earth named after?
All of the planets, except for Earth, were named after Greek and Roman gods and godesses. The name Earth is an English/German name which simply means the ground. It comes from the Old English words ‘eor(th)e’ and ‘ertha’. In German it is ‘erde’.
Where is the center of Earth?
Earth’s core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth’s surface, and has a radius of about 3,485 kilometers (2,165 miles).
Which country is heart of Earth?
Woods, a physicist with Gulf Energy and Environmental Systems in San Diego, California, used a digital global map and calculated the coordinates on a mainframe system as 39°00′N 34°00′E, in modern-day Turkey, near the district of Kırşehir, Kırşehir Province, approx.
Which is the hottest part of the Earth?
Death Valley, California. According to the World Meteorological Organization’s Global Weather & Climate Extremes Archive, temperatures in Death Valley reached international extremes when they hit 134 degrees Fahrenheit in 1913 — the hottest temperature recorded anywhere in the world.
Why is Earth hot inside?
There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements.
