What is the definition for Nuclear fusion?

• State of matter
• The process in which two atomic nuclei combine to form a larger nuclear releasing hude amounts of energy in the process
• Huge exsplosion
• cloud-like region of gas

How are elements created in stars?

• Stars create new elements in their cores by squeezing elements together in a process called nuclear fusion. First, stars fuse hydrogen atoms into helium. Helium atoms then fuse to create beryllium, and so on, until fusion in the star’s core has created every element up to iron.

What are the results of fusion in large stars?

• Big Boom
• c2
• Hydrogen fusion (nuclear fusion of four protons to form a helium-4 nucleus) is the dominant process the generates energy in the cores of main-sequences stars. … As a result, there is little mixing of fresh hydrogen into the core or fusion products outward.

Two small nuclei collide and fuse, forming a what?

• May be released
• A higher atomic number

Two largher nuclei collide and fuse.forming what?

• A still large nucleus
• reaction that create the heaviest elements

What elements can be produced by stars the size of the sun?

• The fusion connects with the wrong thing and explode 
• Fusion in the early Universe produced hydrogen, helium, lithium, beryllium andboron, the first 5 elements in the periodic table. Other elements, from carbon to iron, were formed by fusion reactions in the cores of stars.

Where are elements heavier than iron  produced?

• The supernova will begin the rise until it explode
• All of the post-iron elements are formed in supernova explosions themselves. So much energy is released during a supernova explosion that the freed energy and copious free neutrons streaming from the collapsing core drive massive fusion reactions, long past the formation of iron.

What elements may have formed in this supernova that would not have formed in a smaller star?

• The lightest elements (hydrogen, helium, deuterium, lithium) were produced in the Big Bang nucleosynthesis. According to the Big Bang theory, the temperatures in the early universe were so high that fusion reactions could take place. This resulted in the formation of light elements: hydrogen, deuterium, helium (two isotopes), lithium and trace amounts of beryllium.
• The lightest elements are, nitrogen, oxygen, gas, liquid, and solid. 

What is the definition of supernova?

• a big star that explodes
• a star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass.
