fusion reactions in stars
What else can I help you with?
Fusing hydrogen atoms into heavier elements produces?
Fusing hydrogen atoms into heavier elements produces helium and releases a large amount of energy in the form of heat and light. This process, known as nuclear fusion, occurs in the core of stars like our sun and is responsible for the sun's energy output.
What produces all the known elements in the universe besides hydrogen?
Most known elements in the universe are produced through stellar nucleosynthesis during the life cycles of stars. Elements like helium, carbon, and oxygen are formed through nuclear fusion in stars. Heavier elements, such as iron, are created in supernova explosions, while even heavier elements can form through processes like neutron capture in events such as neutron star mergers. These processes contribute to the chemical diversity of the universe, enriching interstellar matter with elements that will eventually form new stars, planets, and life.
What chemical element is the primary constitutent of a young star?
In the current stage of the Universe, stars start off with lots of hydrogen-1 - and that's what they first fuse, since fusing heavier elements requires higher temperatures.Actually, hydrogen-2 (also known as deuterium) is even easier to fuse, but stars don't have significant amounts of that.
What is the lightest element in the universe?
Hydrogen. It is the lightest element in the known universe.
How many elements in the universe do we know of?
As of now, there are 118 known elements in the periodic table, ranging from hydrogen (atomic number 1) to oganesson (atomic number 118). These elements are categorized into metals, nonmetals, and metalloids, and they make up all matter in the universe. While scientists continue to explore the potential for synthetic elements and the existence of unknown elements under extreme conditions, the currently recognized elements are well defined. However, new discoveries in astrophysics and particle physics may reveal more about the fundamental building blocks of the universe.

Is hydrogen the newest element?
Hardly. Hydrogen is one of the oldest elements known. It also comprises more than 98% of the matter in the entire known universe.

Does the first eighteen elements in the periodic table make up most of the matter of the known universe?
Yep. In fact, hydrogen alone makes up most of the matter in the known universe. Hydrogen is what the stars are made up of, and let's face it, stars are pretty big, and there's a bunch of them. Anything heavier than hydrogen (all the remaining elements) are products of nuclear fusion within stars, which has been going on since the beginning of the universe (15 billion years or so.)
99 percent of the known matter in the universe?
is found in the form of hydrogen and helium. These elements were created during the Big Bang, and all other elements found in the universe were formed through processes like nuclear fusion in stars. Only a small fraction of the universe is made up of heavier elements like carbon, oxygen, and iron.
What chemical element is the primary constitutent of a young star?

What are the two lightest gases in the universe?
In our known universe, hydrogen then helium. But this may change with further exploration.
The lightest known element with only one proton is?
Hydrogen is not only the lightest but the only known element with only 1 proton per atom.
What is the lightest element in the universe?
Hydrogen. It is the lightest element in the known universe.
What process produces the largest amount of energy given off by stars?
Nuclear Fusion
What fraction of the mass in the known universe is made up of hydrogen and helium?
By mass, hydrogen = 75%, helium = 23%.
