Pseudo Noble Gas Electron Configurations
We've learned about electron configurations, and also about how this plays into ionization, given that elements will tend to ionize in such a way so as to achieve noble gas electron configuration. But certain transition metals will seek...

VSEPR Theory and Molecular Geometry
Did you know that geometry was invented by molecules? It's true! Until the first stars went supernova and littered all the elements across the cosmos, everything was simply spheres, from protons to stars. But then, under cooler planetary...
