Inside the Atom: Structure and the Periodic Table: Science Unit 2, Grade 10 (Letters & Devotion)

Description

Inside the Atom: Structure and the Periodic Table is Unit 2 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, 71 pages.

• Subatomic particle counts and their relationship to atomic number, mass number, and charge
• Isotope notation and the neutron-count difference between isotopes of one element
• Electron configuration of main-group atoms
• The historical revision of atomic models in response to specific experimental evidence (gold foil scattering)
• The mechanism underlying periodic trends in atomic radius and ionization energy
• Periodic trends (atomic radius, electronegativity, ionization energy) as a function of table position
• The relationship between atomic emission line spectra and quantized electron energy levels
• The Bohr model versus the electron cloud model as different-purpose simplifications
• Classification of elements by table position (metal/nonmetal/metalloid, group family)
• The relationship between valence electron count and the charge of the ion an atom tends to form

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.
