WebArgument #1: The Atomic Bomb Saved American Lives. The main argument in support of the decision to use the atomic bomb is that it saved American lives which would otherwise have been lost in two D-Day-style land invasions of the main islands of the Japanese homeland. The first, against the Southern island of Kyushu, had been scheduled for ...

Web27 Jan 2024 · The simplest example of the Bohr Model is for the hydrogen atom (Z = 1) or for a hydrogen-like ion (Z > 1), in which a negatively charged electron orbits a small positively charged nucleus. Electromagnetic energy will be absorbed or emitted if an electron moves from one orbit to another. Only certain electron orbits are permitted. cybisthusWebAn atom is the smallest particle into which an element can be divided and still be the same substance.
