The unspoken word of chemistry: Non-stoichiometric. Stoichiometry and non-stoichiometry are concepts that combine to make a solution that does not have to be difficult to understand.
Quantum mechanics is a proverbially and quintessentially challenging topic. It is the poster-child of difficulty in chemistry. Setting up the discussion for the four quantum numbers is fraught with potential and confusion. In this post learn about a different way to teach about orbitals.
Get to zero by becoming neutral. In using this method, let chemistry bring together broader ideas from math, economics and wherever value(s) are expressed in the negative.
Verbal expression is an outward manifestation of internal comprehension. How does it work? That is, what is the method? And what is the mechanism?
Teaching about hypervalent structures is problematic. This post discusses a simple and quick way in determining the number of lone pairs on a hypervalent central p-block atom.
Two groups of students, typically, have difficulty with titrations, the first time around. Those that act too rashly and overshoot the endpoint, and those over-cautious ones who they take forever to finish.
