The following is the answers to Questions on Basic Covalent Bonding LDS Notes PPT.
1a) "ionic bond", "Metallic bond", Covalent bond
1b) Covalent bond
2) ΔEN < 1.7
3) Lewis Dot Structure (LDS), VSEPR (Valence Shell Electron Pair Repulsion), and Hybridization
4a) LDS - shows the atoms that shared electrons and how many shared electrons and how many unshared pair (Lone Pair, LP) on each atom
4b) VSEPR, shows the geometry of the substance (in other words the shape)
4c) Hybridization - theory behind this model
5) Molecular compounds (MC) and Polyatomic ions
6) After ”bonding” (movement of ve- ), all atoms need 8 ve- around them either shared and/or unshared except H (2ve-), Be (4ve-), B (6ve-) and elements in the 3rd row of Periodic Table or greater than exceed 8ve-
7) False, LDS only show valence electrons
8) Will discuss
9) LDS is part of a Chemical Bonding Model that explain how substance share valence electrons.
10) Can not see Coordinate Covalent Bond (a bond that both shared electrons came from one of the two atoms).
