HOW CHEMICAL ELEMENTS FORMED

Birth of chemical elements

• LIGHT ELEMENTS ARE FORMED AS A RESULT OF FUSION IN STARS.
• stars like the sun, fuse hydroegen nuclei - into helium and similar small nuclei eg carbon
• when it becaomes a Red Giant- it fuses Helium and other small nuclei into larger nuclei. 

• NUCLEI LARGER THAN IRON CANNOT BE FORMED because TOO MUCH ENERGY is needed. 

• HEAVY ELEMENTS ARE FORMED when a MASSIVE STAR COLLAPSES AND EXPLODES as a SUPERNOVA
• the large force of the collapse fuses into small nuclei INTO LARGER NUCLEI THAN IRON.
• the explosion…
