Why is the Incorrect Atomic Model disproved because the uncertainty in the velocity of the electron is greater than the speed of light? What is important about the speed of light that disproves this model?
Nothing with rest mass can have a higher velocity than the speed of light. Because an electron’s mass can be determined, as it exists when it is at rest, it is said to have rest mass. Light, on the other hand, ceases to exist when it is not moving and can therefore not be weighed, therefore having no rest mass.
The speed of light is the fastest speed that anything can go. In fact, light and photons are the only things that can travel at the speed of light. It is not physically possible for things with rest mass, like electrons, to move at or faster than this speed. Therefore, this theory is proved incorrect because the speed of light acts as a limit that cannot be reached or passed.
How close to the speed of light is "too close" for it to be considered realistic?
Nothing can go faster than the speed of light, so since the model shows the velocity of the electron as being faster, it was disproved.
