Atomic Bombs
no
Atomic bombs use nuclear fission, where heavy atomic nuclei split into smaller ones releasing energy and radiation. Hydrogen bombs use both nuclear fission and fusion, with fusion reactions involving the combining of light atomic nuclei to release even more energy and radiation. Hydrogen bombs are typically more powerful and produce higher levels of radiation compared to atomic bombs.
Hydrogen bombs still exist and are considered among the most powerful weapons in the world. These bombs use nuclear fusion to release an immense amount of energy, and they are designed to create explosions far more destructive than atomic bombs.
