1 Do Now Which substance contains bonds that involved the transfer of electrons from one atom to another? 1. CO 2 2. NH 3 3. KBr 4. Cl 2 When sodium and fluorine combine to produce the compound NaF, the ions formed have the same electron configuration as atoms of 1. argon, only 2. neon, only 3. both argon and neon 4. neither argon nor neon

2 Williamsburg High School for Architecture and Design Mr. Quinn and Ms. Tom 11/13/13

3 Aim What happens after an atom steals or loses electrons?

4 From Yesterday… All elements want to look like noble gases They can either gain or lose electrons to get there

5 Lewis Structures II: The Return

6 Terminology Ionic Bond Valence electrons are transferred Attraction is electric

7 Helpful Visuals

8 Lewis Structures III: The Return II

9 A&D vs. Regents, Round 1 An ionic compound is formed when there is a reaction between the elements 1. strontium and chlorine 2. hydrogen and chlorine 3. nitrogen and oxygen 4. sulfur and oxygen

10 A&D vs. Regents, Round 3 Which Lewis electron-dot diagram represents a molecule having an ionic bond?

11 A&D vs. Regents, Round 2 The bonds in BaO are best described as 1. covalent, because valence electrons are shared 2. covalent, because valence electrons are transferred 3. ionic, because valence electrons are shared 4. ionic, because valence electrons are transferred

12 A&D vs. Regents, Round 4 Which Lewis electron-dot diagram represents calcium oxide?

13 A&D vs. Regents, Round 5 Which element forms an ionic compound when it reacts with lithium? 1. K 2. Fe 3. Kr 4. Br
