The sun is the example where fusion takes place via:

Correct answer: D. Only A & B

  • A. Proton - proton cycle
  • B. Carbon- carbon cycle
  • C. Co-co cycle
  • D. Only A & B

Explanation

So, in the core of the Sun, there are high temperatures and pressures that allow for nuclear fusion to occur. The proton-proton cycle is the most dominant fusion process in the Sun, where hydrogen nuclei (protons) combine to form helium nuclei. On the other hand, the carbon-nitrogen-oxygen (CNO) cycle is a secondary fusion process that involves carbon, nitrogen, and oxygen isotopes. Both processes release a tremendous amount of energy, powering the Sun and providing us with warmth and light. It's like the Sun's own stellar power plant.

About Composition of Atomic Nuclei

Atomic nuclei contain positively charged protons and electrically neutral neutrons, collectively called nucleons. Questions use atomic number, mass number and nuclear notation to identify isotopes, isobars and isotones, and may connect nuclear composition with nuclear charge, mass defect, binding energy and the stability of the nucleus.
