All elements past hydrogen are formed in stars. During the main stage of stars life, it fuses hydrogen into helium. Once it runs out of Helium to fuse, it begins fusing Helium into heavier elements. This continues until iron is formed. Iron gains no energy from fusion, so fusion stops. If the star is massive enough, it will explode in a supernova. The extreme heat can cause the iron to fuse into even heavier elements.

What is made up of radioactive elements?
Radioactive elements are naturally occurring elements with unstable atomic nuclei that emit radiation as they decay. Common examples include uranium, thorium, and radium. These elements can be found in minerals, rocks, and soil.
Name the four most common elements?
Carbon, Hydrogen, Nitrogen, and Oxygen are the four most common elements.
Where were the commonest elements made?
Common elements like hydrogen and helium were primarily formed during the Big Bang, the initial explosive event that created the universe. Elements heavier than helium are formed in the cores of stars through nuclear fusion reactions. Very heavy elements are produced in supernova explosions.
What are the 5 common elements?
The five common elements are oxygen, carbon, hydrogen, nitrogen, and calcium.
What elements are made up of monecules?
Elements are made up of atoms, not molecules. Atoms are the smallest unit of an element that retains its properties. When atoms of different elements combine chemically, they form molecules.
