Covalent Bonding How atoms share electrons. Very simple covalent bonds Two atoms share electrons to get a valence “Octet” Cl - Cl.

CHEMICAL BONDS Atoms must have a complete outer energy level to be stable Most atoms of elements: 1.are not stable 2.will need to gain, lose, or share.

Naming Compounds Unit 2 Chemistry. Covalent Nomenclature What is a covalent bond????

Bonding Exercises. Using Chapter 5 and Chapter 6.1 find definitions of the following: Electronegativity First Ionization Energy Valence Electron Cation.

Covalent Bonding. Covalent Bond: –a bond formed by the sharing of electrons between atoms. (does NOT form charges) –Made up of nonmetals Molecule: a neutral.

Bonding. Think of some properties of salt Forms crystals Brittle Hard Solid High melting and boiling point Forms an electrolyte (conducts electricity.

Nomenclature Naming compounds. Ionic Compounds Cation (metal): The name of the element stays the same Anion (non-metal): Change the ending of the element.

Ionic and covalent compound nomenclature. Naming ionic compounds General rule: 1.State the cation’s element name 2.State the anion’s element name but.

Vocabulary Polar bond Nonpolar bond Ionic bond Covalent bond Ions Cation Anion Atomic radium Ionic radius Isoelectronic series Ionization energy Electronegativity Atomic Lewis structure Ionic Lewis structure Valence electrons Core electrons Octet rule Polar bond Nonpolar bond Ionic bond Covalent bond 34 polyatomic ions Covalent network Ionic structure Metal bond Hydrogen bond Dipole –dipole Dispersion Type I Ionic compound Type 2 Ionic compound Polyatomic ion compound Covalent compound Binary Acid Oxyacid Mono Di Tri Tetra Penta Hexa Hepta Octa Nona Deca Ionic Nomenclature Rules Covalent Nomenclature Rules Acidic Nomenclature Rule

Skills Identify Type of ion atoms form from periodic table, including “W” of fixed charges Compare atoms wrt atomic size/radii, ionic size/radii, ionization energy, or electronegativity to identify which is higher and be able to justify based on atomic structures. Know names and formulas of 34 polyatomic ions Draw lewis structures for atoms, ions and ionic compounds. Identify a chemical bond as nonpolar, polar or ionic Describe the 6 types of intermolecular forces and the requirements for each.

Skills Identify the dominant intermolecular force for a compound. Compare the IMFs for two compounds to determine the stronger or weaker IMF. Identify a substance with a higher or lower physical property base on relative IMF. Identify a substance as acidic, covalent or ionic based on its formula. Use the 7 nomenclature rules to convert between names and formulas. 3 ionic rules, one covalent rule, 3 acid rules Know the 4 accepted exceptions to the 7 nomenclature rules.

Exit Slip - Homework Exit Slip: Draw the ionic Lewis structure for the compound that forms between magnesium and bromine. What’s Due? (Pending assignments to complete.) Study for U4 Test on Tuesday What’s Next? (How to prepare for the next day) Read Holt p159-175
