Bonds in limbo

Students will answer questions about the online Science News article “This weird chemical bond acts like a mash-up of hydrogen and covalent bonds,” which explores new research that suggests chemical bonds exist on a continuum. A version of the story, “Chemical bond acts like a mash-up,” can be found in the January 30, 2021 issue of Science News.

Accepting the exceptions

Students will discuss the classical definitions of chemical bonds and determine how to adjust those definitions based on new research. Then, students will talk about the best strategies for assessing general chemistry concepts and exceptions to those generalizations.
