How are most of the elements with nuclei heavier than those of hydrogen and helium formed?
Well, Helium is an element, and "substance" can mean a combination of elements and compounds... which are formed according to their chemical properties.
Assuming you were asking about pure elements, rather than substances, all elements up to Iron-56 are formed by nuclear fusion, presumably inside of stars. This is due to to Iron-56 being the most stable nucleus in the Periodic Table. Hydrogen-1 forms Helium-4, Helium combines to form Beryllium-8, Carbon-12, and Oxygen-16. And so on.... up to Iron-56.
Fusion of heavier compounds will not result in excess energy (e.g. a star's heat and light) so those nuclear reactions will not sustain a star.
Therefore, all elements heavier then Iron-56 are formed by the extraordinary conditions of a super nova. Because earth has abundant elements heavier than Iron-56, it is thought that the matter in our Solar System has been through several solar cycles... In other words, "we are all made of stars".

Which of these elements does this star contain?
Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).
Explain how heavier elements are formed from hydrogen within the core of a star?
Heavier elements are formed through nuclear fusion reactions in the core of a star. Hydrogen atoms are fused together under high pressure and temperature to form helium. Further fusion reactions involving helium nuclei lead to the formation of heavier elements like carbon, oxygen, and up to iron. These elements are produced through a series of nuclear reactions that occur as the star evolves.
Do all stars turn hydrogen in to helium?
No, not all stars turn hydrogen into helium. Stars like our Sun do convert hydrogen into helium through nuclear fusion in their cores. However, more massive stars can undergo further fusion reactions involving helium, producing heavier elements like carbon, oxygen, and even iron.
What are the 2 main elements in stars?
All stars are comprised of around 98% hydrogen and helium, of which approximately 3/4 is hydrogen.This is also true of all the matter in the universe as a whole.While stars contain some amount of pretty much every element, they are made primarily of hydrogen and helium.
Why do all stars have hydrogen and helium?
Hydrogen and helium were the first elements formed after the Big Bang, and they continue to be the most common elements in the universe due to their abundance. Stars form from clouds of gas and dust in space, and since hydrogen and helium are the most abundant elements available, they make up the majority of a star's composition.
What is the sun formed from?
hydrogen, helium, and a small amount (less than 2%) of heavier elements
How are heavier elements formed from hydrogen within the core of a star?
Heavier elements are formed through nuclear fusion processes that take place in the core of a star. Hydrogen atoms undergo fusion to form helium, and then this process continues to create heavier elements by fusing helium atoms together. As the star fuses lighter elements, it produces heavier elements through a series of nuclear reactions.
What does nucleur fusion create inside stars?
First hydrogen nuclei fuse to form helium, and then as the star ages heavier and heavier elements are formed.
What are the two main elements of the sun?
Hydrogen and Helium. Also comprised of a core of much heavier elements, all the elements in the universe heavier than hydrogen probably came from supernovae.
Where did most of the elements heavier than Hydrogen and Helium form in the Universe?
Elements heavier than hydrogen and helium primarily formed in the cores of stars through nuclear fusion processes. Elements up to iron are formed in the cores of stars, while elements heavier than iron are typically produced in supernova explosions or neutron star mergers. These heavy elements are dispersed into space during these catastrophic events, enriching the interstellar medium from which new stars and planets can form.
Is it true that Hydrogen and Helium were formed by nuclear reaction in the stars and other elements were formed after the Big Bang?
Close, but not exactly. Hydrogen is not formed by nuclear reactions in stars, hydrogen was formed not long after the Big Bang, when the expanding universe had cooled sufficiently that an electron and a proton could combine to form a hydrogen atom. Helium and all the other elements that are heavier than hydrogen, were formed by the process of nuclear fusion, in stars.
What is the fuel of a star in space?
Hydrogen , Helium and a few heavier elements.
Was carbon the first atom created after the big bang theory?
No, carbon was not the first atom created after the Big Bang. The first atoms that formed were hydrogen and helium, and heavier elements like carbon were produced later through processes like stellar nucleosynthesis in the cores of stars.
What elements are formed in cool stars?
In cool stars, elements such as hydrogen and helium are primarily produced through nuclear fusion in their cores. Elements heavier than helium (e.g., carbon, oxygen, and iron) are formed through nucleosynthesis processes during the later stages of a star's lifecycle, such as in red giant stars or during supernova events.
How are elements beyond hydrogen and helium formed?

Why does your sun have 2 percent heavier elements and from where do they come?
I think it's our Sun which gets heavier elements from fusion of hydrogen and other light elements.Edit: Our Sun does create helium from hydrogen by fusion, but that's all. The reason it has heavier elements is that these come from the nebula that formed the Sun. The heavier elements are thought to have come from stars that exploded as "supernovas", a long time ago.
