Where are gases like hydrogen and helium most abundant?
Hydrogen and helium are the first elements produced in the universe after the big-bang.
what's the meaning of primordial helium?
Primordial helium refers to the helium that was formed during the Big Bang nucleosynthesis, approximately 3 to 20 minutes after the Big Bang. This process produced about 25% of the universe's mass in helium, along with hydrogen and trace amounts of other light elements. Unlike helium produced in stars (stellar helium), primordial helium is a remnant of the universe's early conditions and is found in the interstellar medium and as part of the cosmic background. It plays a crucial role in understanding the universe's evolution and the formation of cosmic structures.
Why is there an abundance of lighter elements in the universe?
The light elements come from the very origin of the Universe. Hydrogen, being the simplest element, is still the most common element in the Universe. During the heat of the Big Bang, some Helium was produced, but almost no metals (i.e., heavier elements).The reason we have relatively few hydrogen and helium on Earth is because most of it must have escaped to space during the formation of Earth. More massive planets, like Jupiter, have a much larger percentage of hydrogen and helium.
Where did hydrogen and helium in the universe come from?
Hydrogen and helium were mainly produced during the Big Bang, the event that created the universe. Roughly 75% of the normal matter in the universe is hydrogen and about 25% is helium. These elements have since played a fundamental role in the formation and evolution of all other elements in the universe through processes like nuclear fusion in stars.
What are the seven elements that make up the universe?
The seven elements that make up the universe are hydrogen, helium, oxygen, carbon, nitrogen, iron, and silicon. These elements are the building blocks of all matter in the universe.

The two elements most abundant in the universe are?
Hydrogen and helium are the two most abundant elements in the universe.
What are the four main physical elements of the universe?
Hydrogen, helium, oxygen, and carbon are the most abundant elements in the universe.

How plentiful is helium?
Helium is relatively abundant in the universe but rare on Earth. It is primarily produced through the natural radioactive decay of heavier elements like uranium and thorium. However, because helium is light and easily escapes Earth's atmosphere, it is becoming increasingly scarce as a non-renewable resource.
Is helium a rare gas?
Helium is the lightest member of noble gases. Due to the atmospheric pressure on Earth, helium does not exist on the Earth's surface. On the other hand, helium is the second most abundant element in the universe.
What are likely the two most abundant elements in the universe?
Hydrogen and Helium. :)
Two most common elements in universe?
Hydrogen, followed by helium.
How is helium formed in the universe?
Helium is formed in the universe through nuclear fusion processes that occur in stars. During the fusion of hydrogen atoms in the core of a star, helium is produced as a byproduct. This process releases a large amount of energy and is responsible for the creation of helium in the universe.
