Presentation transcript:

Types of Bonding Chemical Bond: Chemical Formula: attraction b/w the nuclei & valence e- of different atoms thus binding atoms together. Chemical Formula: represents #s of atoms of each kind in compound by using symbols & # subscripts.

What does electronegativity mean again?

What group is the most stable?

Bigger Electronegtivity Value – Smaller Electronegitivity Value Type Ionic Covalent Determine Electronegitivity Difference of : 3.3-1.71 1.70-0 Practice: Bigger Electronegtivity Value – Smaller Electronegitivity Value Na-Cl : K-Br: 3.0 – 0.9 : 2.1 ( ionic) 2.8 – 0.8 = 2.0 ( ionic) Try…P-Cl, Li-F, Mg-O, & I-Br P-Cl: 3.0 – 2.1 = 0.9 ( covalent) Li-F: 4.0 – 1.0: 3.0 (ionic) Mg-O: 3.5 – 1.2 = 2.3 (ionic) I-Br: 2.8-2.5 = 0.3 (covalent) Description ●Cation electrically attracted anion ●Metal (+) gives its valence electrons to nonmetal(-) ●Share of electrons; ●Nonmetal shares electrons w/ another Nonmetal

Type Ionic Covalent Structure VSEPR: see later notes

Type Ionic Covalent Beaker A: Table Salt ( NaCl) Properties Strong Electrical Attraction High Melting & Boiling Point Hard but Brittle Dissolve in H2O: ions break apart Conductors: only in liquid state - Melted or dissolved - Need FREE metal ions Strong Bond Interaction between 2 or more molecules is weaker than ionic Low Melting Point Low Boiling Point Demo Beaker A: Table Salt ( NaCl) Beaker B: Table Salt (NaCl) dissolved in H2O Beaker C: Sugar (C6H12O6) Beaker D: Sugar (C6H12O6) dissolved in H2O Questions: What did you observe for each beaker? Explain why these observations make sense.
