Problem 52E
Energy Changes in Nuclear Reactions (Section)
The isotope 62 28Ni has the largest binding energy per nucleon of any isotope. Calculate this value from the atomic mass of nickel-62 (61.928345 amu) and compare it with the value given for iron-56 in Table.

General Chemistry: Chapter 1 Reading Notes By Madelyne Crawford, August 25 The following notes were acquired from Chemistry: A Molecular Approach Textbook by Nivaldo J Tro. The reading was to be completed by Monday, August 29. Overview/Review of Chapter 1 The main goal of chemistry is to analyze and study the behavior of matter by understanding the behavior of atoms and molecules The scientific approach to knowledge is based on observation and experiments Qualitative vs. quantitative: o Qualitative describes how a process happens o Quantitative measures something about the process A hypothesis is an interpretation of observations that explains scientific findings
