Verified by Toppr

Nuclear fusion is a nuclear reaction in which two or more atomic nuclei at a very high speed and join to form a new type of atomic nucleus. Fusion reactions are high energy reactions in which two lighter atomic nuclei fuse to form a heavier nucleus. This fusion reaction is taking place inside the sun core as hydrogen nuclei.
