Answer:
Explanation:In terms of what happens in the reactions of nuclear fusion is that it produces fewer radioactive particles than nuclear fission. The types of atoms involved in nuclear fusion is the making of two or more lighter atoms into a larger one. In nuclear fission, the larger atom is split up into two or more smaller ones. The conditions necessary to start the reactions in nuclear fusion is a high temperature or high density environment. In a nuclear fission, the conditions need to be high-speed neutrons. The safety concerns associated with each is that it creates waste material that is dangerous, like harmful radiation that stays active for 50 - 100 years
