Chemical Bonding: Why and How Atoms Connect: Science Unit 3, Grade 10 (Letters & Devotion)

Description

Chemical Bonding: Why and How Atoms Connect is Unit 3 of Chemistry in the Kitchen and Beyond: Matter, Energy, and Change (Part 1) (Grade 10), the Letters & Devotion Science course, complete in one printable PDF: 10 lessons, the unit check-up and the answer key, 77 pages.

• Valence electron count and its relationship to group number and bonding tendency
• Charge-balancing procedure for binary ionic formula units
• Lewis structure construction procedure for simple covalent molecules
• Electrostatic stability as the causal mechanism for electron transfer/sharing
• Electronegativity difference as the basis for bond-type classification along a continuum
• The distinction between individual bond polarity and overall molecular polarity as determined by shape/symmetry
• Polyatomic ion naming and formula-writing convention, including use of parentheses for multiple polyatomic units
• The causal link between bond/structure type and macroscopic properties (melting point, conductivity, solubility)
• Textual evidence in scientific explanatory text signaling the limits of a simplified bonding model
• Relationship between ionic charge magnitude and lattice attraction strength (qualitative)

Every lesson is written for a parent with no teaching background: it opens with a short script to read aloud, names the specific wrong idea a student is likely to reach for and how to correct it, and closes with a practice sheet you may copy for your household. Scripture references are King James Version throughout. Black-and-white, 8.5 x 11 in. The whole year of this course is also in this store as a single book.
