Nuclear fusion is a process where light atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy. In the Sun, this process is primarily the proton-proton chain, where four hydrogen nuclei (protons) ultimately fuse to form one helium nucleus.
The process that is responsible for the generation of energy within the core of the sun is:

- Consider the following statements: 1. In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. This is how the sun produces energy. 2. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. Nuclear power plants use nuclear fission to produce electricity. Evaluate the statements
