From Mendeleev’s original design to physicist-favorite “left-step” rendition, the periodic table of elements has gone through many iterations since it was first used to organize elements 150 years ago - each with its own useful insights...

SUMMARY

In this video, I show Why Some Reactions EXPLODE and Others COOL: Root Cause of Chemical EnergyI I show how the chemistry behind endothermic and exothermic reactions can be traced to the underlying quantum...

Electron Configurations are essential to chemistry and they help us better understand and explain the position/location of electrons. Writing electron configurations can be daunting at first but once you see the pattern, you will be able...

Everyone has trouble with electron configurations and quantum numbers. Well today we are going to settle the score with a little practice!

Orbitals! Oh no. They're so weird. Don't worry, nobody understands these in first-year chemistry. You just pretend to, and then in second-year you learn them a little better, the following year a little better, and once you have a PhD...

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...
