How many atoms are in an atombomb?

The number of atoms in an atomic bomb varies depending on its design and the materials used, but a typical fission bomb can contain about 10 to 20 kilograms of fissile material, such as uranium-235 or plutonium-239. Given that one mole of a substance contains approximately (6.022 \times 10^{23}) atoms, a bomb containing around 20 kilograms of uranium could contain roughly (7 \times 10^{24}) atoms. However, this is a simplified estimate, as the exact number can vary based on the bomb's specific design and composition.
