🔍 Key Concepts

• energy stored in bonds between atoms • difference between motion energy vs stored energy • how molecules form from individual atoms

💭 Think About

• When atoms join together to form molecules, is energy mainly about motion, position, or the bonds themselves? • Which type of energy is specifically related to the arrangement and bonds of atoms in a substance? • Think about what kind of energy is released or absorbed during a chemical reaction—what do we usually call that?

✅ Before You Answer

• Identify which option refers to energy of motion and rule it out if it doesn’t fit atom bonding. • Identify which option refers to stored energy in the bonds of substances. • Ask: during chemical reactions, what form of energy is involved when bonds are broken or formed?
