What astrophysicist first advanced the idea that the chemical elements originated from hydrogen in stars?
Fred Hoyle is credited with advancing the idea that the chemical elements originate from hydrogen in stars. He proposed the concept in his groundbreaking work on stellar nucleosynthesis.
How did the elements get to be part of earth?
The elements that make up Earth were formed during the process of stellar nucleosynthesis in the core of ancient stars. These elements were then scattered into space through supernova explosions and eventually coalesced into the Sun and the planets, including Earth. The composition of Earth's elements reflects the chemical diversity present in the universe.
A large cloud of dust and gas that becomes a star?
This process is called stellar nucleosynthesis. It occurs when gravity causes a cloud of dust and gas to collapse in on itself, leading to high temperatures and pressures at the core. This triggers nuclear fusion reactions that convert hydrogen into heavier elements and release energy, ultimately forming a new star.
Stars combine Hydrogen to make Helium during nuclear fusion. Living things are made of heavier elements like Carbon Oxygen Iron and Calcium. How did these elements form?
These heavier elements were formed through processes like nucleosynthesis in the core of massive stars, supernova explosions, and stellar winds. These events create conditions where lighter elements are fused or broken apart to form heavier elements, eventually leading to the creation of elements like carbon, oxygen, iron, and calcium.
How and where did the natural elements form?
Most of the atoms in living things come from just six elements. These elements are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. Scientists theorize that these elements, along with all 93 natural elements, were created in the centers of stars billions of years ago, shortly after the universe formed in a violent explosion.
Where did all the elements, other than hydrogen and helium, originate from?
Elements other than hydrogen and helium originated from nuclear fusion processes in the cores of stars through a process called stellar nucleosynthesis.
What are two most common elements in nebulas?
The two most common elements found in nebulas are hydrogen and helium. These elements are the building blocks of stars and galaxies, and are formed during the process of stellar nucleosynthesis.
What produces all of heavy elements required for life?
it is the cycle of stellar evolution
Define the stellar theory?
If your referring to Stellar Nucleosynthesis, then its when stars fuse the smaller elements (Hydrogen,Helium) to make the heavier elements (iron, gold, silver,zinc, etc).
At the beginning of the universe scientists believe that stellar evolution contained only what two elements?
Scientist believe that stellar evolution contained only hydrogen and then helium.
How were chemical elements larger than helium made?
This process is called stellar nucleosynthesis.
How are natural elements heavier than iron created?
The process is called stellar nucleosynthesis.
What are two elements which are abundant in nebulae?
Ionized hydrogen and helium are the most abundant chemical elements in nebulae.
Where were the elements that are found in nature formed'?
Hydrogen and helium are thought to be formed during the Big Bang. We also know that helium is formed in stars during the process of stellar evolution. The other elements formed in stars during stellar evolution and end-of-life stellar events (like a supernova). It could be said that with the exception of hydrogen, all the elements formed in stars during one phase or another of the life of stars. This though minute quantities of some isotopes that are found in nature appear in the decay chains of other isotopes and were not themselves created in stars as described.
Where are naturally occurring elements manufactured?
Naturally occurring elements are created through nuclear fusion in the cores of stars through a process called nucleosynthesis. These elements are then dispersed into the universe through supernova explosions and stellar winds, eventually forming into planets.
How are elements formed from hydrogen?
Heavier elements are formed from hydrogen, the most abundant element in the universe, through a process called nuclear fusion. There are machines or structures in the universe that do this, and we call them stars. It is the process within stars, stellar nucleosynthesis, that allows heavier elements to be created up through iron. Elements heavier than iron are formed in supernova events.

What elements were formed during stellar evolution?
Everything except Hydrogen & Helium (and part of the Helium is also formed within stars).
