Where Found Charge Mass Number Proton 1 1 Neutron 0 1 Electron Electron Cloud 0. At the start of WWII in 1939 the atomic bomb had not yet been invented. However, scientists discovered about that time that a powerful explosion might be possible by splitting an atom. This type of bomb could destroy large cities in a single blast and would change warfare forever!. Lab no. 6. In . analytical chemistry. , . Atomic absorption spectroscopy.
