Details Description Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach. This Science Object is the second of three Science Objects in the Atomic Structure SciPack. It explores the structure-related properties that make one type of atom different from another, and looks more closely at the role of the neutron. The number of protons in the nucleus determines what an atom's electron configuration can be and so defines the element and its properties. NSTA Learning Center
