👉 The nuclear weapon, also known as a nuclear bomb or atom bomb, is a highly destructive weapon that utilizes nuclear reactions to release enormous amounts of energy. It operates on the principle of nuclear fission or fusion, where atomic nuclei are split or merged, respectively, resulting in a massive release of energy in the form of heat and radiation. This energy is then converted into explosive force, producing intense heat that vaporizes materials and creates a powerful shockwave. Nuclear weapons are categorized into fission bombs, which use fission reactions, and fusion bombs (or hydrogen bombs), which combine both fission and fusion processes. Due to their immense destructive power, nuclear weapons have significant geopolitical implications, serving as a deterrent in international relations but also posing severe risks of catastrophic loss of life and environmental damage.
