What is the highest abundance?
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 are the four most abundant?
The four most abundant elements by mass in the human body are oxygen, carbon, hydrogen, and nitrogen. These four elements make up about 96% of the human body.
What element is most abundant universe?
Hydrogen
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 element is most abundant in Earth’s atmosphere?
Nitrogen
The most abundant naturally occurring gas is Nitrogen (N2), which makes up about 78% of air. Oxygen (O2) is the second most abundant gas at about 21%. The inert gas Argon (Ar) is the third most abundant gas at . 93%.
What are the 5 most abundant elements on Earth?
10 Most Abundant Elements In Earth’s Crust
- Oxygen – 46.1%
- Silicon – 28.2%
- Aluminium – 8.23%
- Iron – 5.63%
- Calcium – 4.15%
- Sodium – 2.36%
- Magnesium – 2.33%

What does the most abundant mean?
1 : existing or occurring in large amounts : ample abundant rainfall abundant food. 2a : marked by great plenty (as of resources) a fair and abundant land. b : amply supplied : abounding an area abundant with bird life.
Why is oxygen so abundant in the universe?
The abundance of oxygen in the universe is a consequence of the inner workings of stars. Stars are, in a way, elemental factories, taking light elements like hydrogen and helium and fusing them together to form all the elements ranging up to iron.
What is the rarest element on Earth?
astatine
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth.
Why there is no oxygen in the space?
We’re able to breathe on earth because the atmosphere is a mixture of gases, with the thickest gases nearest the earth’s surface, giving us the oxygen we need to breathe. In space, there is very little breathable oxygen. This prevents the oxygen atoms from joining together to form oxygen molecules.
What are the 3 most abundant elements in the universe?
The majority of elements in the universe are gases. The first three most abundant elements in the universe are hydrogen, helium, and oxygen (in that order).
What is rarest element on earth?
