📚 Topic Summary
Lewis Dot Structures, also known as electron dot diagrams, are visual representations of the valence electrons in an atom or molecule. They help us understand how atoms bond together to form compounds. By showing the arrangement of electrons, we can predict molecular shapes and properties. This worksheet provides practice in constructing these diagrams for various atoms and molecules.

C. Electrons in the outermost shell of an atom that participate in chemical bonding. |
| 4. Covalent Bond |
D. The representation of valence electrons around an atom using dots. |
| 5. Lewis Dot Structure |
E. The tendency of atoms to prefer to have eight electrons in their valence shell. |
📝 Part B: Fill in the Blanks
Complete the following paragraph using the words provided: atoms, electrons, structure, stable, bond.
A Lewis Dot _______ shows how _______ are arranged in a molecule. This arrangement indicates how a chemical _______ forms between _______. The goal of forming a bond is to create a more _______ arrangement of ______.
🤔 Part C: Critical Thinking
