Abstract

Abstract:

Fuzzy representation of chemical concepts is an obstacle for learning, and this prevents students from developing strict logical thought. Inorganic chemistry is one of the basic courses for most of first-year undergraduate students of chemistry and related majors. We dissect four common concepts in inorganic chemistry which are easily confused, point out the reasons for the wrong conclusions and give some teaching suggestions. This article helps teachers for clear presentation of these concepts.

Key words: Thermodynamics, Hydrogen bond, Lanthanide contraction
