📚 Topic Summary
Chemical bonds are the fundamental forces that hold atoms together to form molecules and compounds. These bonds arise from the interactions between the positively charged nuclei and the negatively charged electrons of atoms. The two primary types of chemical bonds are ionic bonds, formed through the transfer of electrons between atoms, and covalent bonds, formed through the sharing of electrons. Understanding these bonds is crucial for predicting the properties and behavior of different substances.
🧪 Part A: Vocabulary

| Term |
Definition |
| 1. Ionic Bond |
A. Sharing of electrons between atoms |
| 2. Covalent Bond |
B. A charged atom or molecule |
| 3. Molecule |
C. Electrical attraction between ions of opposite charge |
| 4. Ion |
D. A group of atoms bonded together |
| 5. Octet Rule |
E. Atoms prefer to have eight electrons in the valence shell |
Match the numbers with the letters. For example: 1 - A, 2 - B, etc.
