This resource, from the Royal Society of Chemistry, is designed to elicit alternative conceptions about ionic bonding that have been found to be commonplace among students. Students are provided with a diagram showing part of a slice through a three dimensional crystal structure of sodium chloride, along with twenty statements which refer to the diagram. Students have to decide whether it each statement is correct or not. The activity explores the extent to which students see ionic bonding in sodium chloride as a molecular phenomenon, with discrete NaCl ion pairs which are internally ionically bonded, but attracted to each other by weaker forces. It may be used with students in the 14–16 age range who have studied chemical bonding, or with post-16 chemistry students.
