Star Formation and Nucleosynthesis Quiz

How is the energy of star produced?

• By combustion

• By decomposition

• by nuclear fission

• by nuclear fusion

Which is the second most abundant element in the universe?

• carbon

• helium

• hydrogen

• oxygen

He successfully carried out a nuclear transmutation reaction, a process of transforming one element or isotope into another element.

• Chadwick

• Moseley

• Mendeleev

• Rutherford

This is known as the origin and production of heavy elements.

• infrared Radiation

• rocks

It was created by bombardment of molybdenum by deuterons (heavy hydrogen, H12), by Emilio Segre and Carlo Perrier in 1937.

• Oxygen

• Helium

• Technetium

• Uranium

This is known as the origin of light elements.

• Stellar Nucleosynthesis

• Primordial Nucleosynthesis

• R-Process

• Supernova Nucleosynthesis

This is also known as Nucleosynthesis.

• S Process

• R-Process

• Nuclear Fission

• Proton-Proton Reaction

What object is formed from gas and dust particles which are pulled together by gravity and no nuclear fusion has happened yet?

• nebula

• main sequence star

• protostar
