Clear up the confusion between ionic and covalent naming rules with this comprehensive, no-prep Covalent Compounds Worksheet! Designed specifically for high school chemistry, this resource guides students through identifying molecular compounds, mastering Greek prefixes, writing chemical formulas, and drawing Lewis structures.

This 4-page worksheet is logically divided into three tiered levels to easily support differentiated instruction in your mixed-ability classroom:

• Level 1: Foundation (Easy)
  • Students practice identifying covalent (molecular) compounds from a mixed list by recognizing compounds made entirely of nonmetals.
  • Includes a matching activity for Greek prefixes (Mono- through Deca-) to help students memorize the foundations of covalent naming.
• Level 2: Intermediate (Medium)
  • Students apply naming rules to write the correct English names for binary covalent compounds, ensuring they use prefixes correctly and apply the "-ide" suffix.
  • Students translate compound names back into their correct chemical formulas (e.g., Dinitrogen tetroxide to N2O4).
• Level 3: Challenge (Hard)
  • Students are challenged to count total valence electrons and draw accurate Lewis structures for molecules like Cl2, H2O, CO2, and CH4.
  • Features a high-level critical thinking prompt asking students to explain why covalent molecular solids have much lower melting points than ionic solids, focusing on the difference between breaking weak intermolecular forces versus strong ionic bonds.

What's Included:

• 4-page printable student worksheet
• A complete, detailed Teacher Answer Key for quick, stress-free grading

Perfect For:

• In-class guided practice or independent work
• Homework assignments
• Ready-to-go substitute teacher plans (Print & Go!)
• End-of-unit review or study guides
