Answers to 2022-2023 Honors Chem328 Review HW for Bonding and Molecular Geometry Test
1) After bonding (moving valence electron, ve-), all atoms want 8ve- around it except H - 2ve-, Be - 4ve-, B - 6ve- and element with 3rd energy level or greater can exceed 8ve-.
2a) i) Cations of the metal element and ii) "sea of free flowing ve- (delocalized ve-)
2b) Will discuss
3a) ions (charged atom or atoms that have lost or gained ve-
3b) Metals - cations
3c) non-metal, gains ve-, anion
3d) ΔEN >= 1.8
3e) The number of each ion needed so the total negative charge equals total positive charge
3f) Will discuss
4a) share, covalent bond, molecule (also polyatomic ions)
4b) ΔEN < 1.8
4c) Subscript is the number of each type of atom that are sharing their ve-
4d) Will discuss
4e) Polyatomic ions. It is different from molecular compounds because the polyatomic ion atoms need more or less ve- to follow the Rule of Eight.
