... • A nuclear reaction involves changes in an atom’s nucleus, usually producing a different element. Chemical reaction never changes the nucleus, it only rearranges the outer shell electrons. – Different isotopes of an element have essentially the chemical reactivity (same electrons), but often have c ...

Unit 2 Overview
... Objective: To gain a deeper understanding of the role that each of the sub-atomic particles plays in controlling chemical behavior. In this unit, we will seek to learn how the three sub-atomic particles control outward chemical behavior in elements. After reviewing the basic structure of the atom, w ...
