Atoms are small enough that attempting to predict their behavior using classical physics – as if they were billiard balls, for example – gives noticeably incorrect predictions due to quantum effects.Through the development of physics, atomic models have incorporated quantum principles to better explain and predict the behavior.

How has the public's phobic fear of radiation fueled governmental over-reaction in Japan?
Before we can answer these questions, we must first learn a few things about radiation and how exposures can occur.
A radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is an atom that has excess nuclear energy, making it unstable.
This excess energy can be either emitted from the nucleus as gamma radiation, or create and emit from the nucleus a new particle (alpha particle or beta particle), or transfer this excess energy to one of its electrons, causing that electron to be ejected as a conversion electron.
What are the “radiation leaks” from the Fukushima accident?
How have misconceptions about radiation, and confusion between radiation and fallout made matters worse than they need to be in the Japanese public mind?
An illustration of the helium atom, depicting the nucleus (pink) and the electron cloud distribution (black).
The nucleus (upper right) in helium-4 is in reality spherically symmetric and closely resembles the electron cloud, although for more complicated nuclei this is not always the case.
After the exposition, the island was set to become a civilian airport—until the United States entered World War II.
