| 1010 - Dot Symbols |
| 1010 - Know that Lewis structures are simple predictors of how atoms form compounds and molecules. |
| 1020 - Know chemical bonds form because they are a more stable arrangement of atoms. |
| 1030 - Understand how ionic bond, covalent bond, and metallic bonding occur. |
| 1040 - Know that valence electrons can be represented with dots around an element symbol. |
| 1050 - Identify and draw atoms with their valence electrons represented as dots (Lewis symbols). |
| 1060 - Define and know the octet rule. |
| 1020 - Bonding |
| 1010 - Draw Lewis structures of ions and ionic compounds containing main-group elements. |
| 1020 - Understand that the formation of an ionic compound from neutral atoms is exothermic. |
| 1030 - Understand the role of lattice energy he amount of energy released is largely due to lattice energy. |
| 1040 - Know the Born-Haber cycle is a way of accounting for the energetics of ionic compound formation. |
| 1050 - Use a Born-Haber cycle to calculate the lattice energy of an ionic compound. |
| 1060 - Know that lattice energy decreases for larger ions and increases with increasing charge. |
| 1070 - Understand why and when ionic solids, solutions, and liquids are electrical conductors. |
| 1080 - Know that most nonmetal atoms prefer an octet of valence electrons (hydrogen requires only two). |
| 1090 - Atoms achieve an octet by forming covalent bonds, a pair of electrons, one from each of two atoms. |
| 1100 - Know why forming covalent bonds is exothermic. |
| 1110 - Atoms can also share two pairs of electrons (a double bond) or three pairs of electrons (triple bond). |
| 1120 - Identify and draw covalent compounds with single, double, and triple bonds. |
| 1030 - Bond Polarity |
| 1010 - Know that a pair of electrons in a covalent bond may be shared unequally, a polar covalent bond. |
| 1020 - Deï¬ne electronegativity (EN) and know its periodic trends. |
| 1030 - Know the electronegativity values of F (4.0), Li (1.0), H (2.1), and Cs (0.7). |
| 1035 - All 2nd period elements differ in EN by 0.5, provide the EN value of any 2nd period element. |
| 1040 - Predict whether a bond is pure covalent bond, polar covalent bond or ionic by electronegativity. |
| 1050 - Define dipole moment and percent ionic character. |
