PPT-Quantum Model of the Atom

The Atom is like a Hotel not a solar system Copy the diagram on the board if you have not done so Electrons do not circle a nucleus willynilly They have assigned positions that only extra energy can cause them to jump into another position ex photoelectric effect . . deformed. . commutators. . with. . macroscopic. . harmonic. . oscillators.

In fact, several theoretical models of the atom have been developed over the last few hundred years.

Rutherford’s experiment suggested that an atom’s positive charge is concentrated in the center of the atom . Known as the “Laughing Philosopher”. “Nothing exists except atoms and empty space; everything else is opinion.”. Created term “. atomos. ” which literally means “not cut” or indivisible.
