The One Nation That Gave Up Its Nuclear Weapons
Nations that develop nuclear weapons often do so as a deterrent to any would-be attacker; it is a significant investment and so these nations, especially the smaller nations on the nuclear list, are threatened by nations surrounding...

Quantum Chromodynamics (QCD)
Electromagnetic force down, three more forces to go! Which one is next? Why it's the strong nuclear force, famous for keeping atomic nuclei together. What kind of particles will be involved in this quantum field theory? Let's find out.

Limitations of VSEPR Theory
We've learned about VSEPR theory, and we know how to use it to predict molecular geometry for a variety of organic molecules. But in fact, there are situations where predictions made with VSEPR theory do not line up with experimental...
