Chemical Reactions Alter Arrangements of Atoms

Chemical Reactions Alter Arrangements of Atoms. Section 7-1. Atoms interact in chemical reactions. How does a chemical reaction produce a new substance? By changing the way the atoms are arranged. Bonds between atoms are broken and new bonds form. This happens when particles collide.
