Gizmos Student Exploration Polarity & Intermolecular Forces 2020 | SCH4U1_Gizmos: Polarity & Intermolecular Forces_Graded A+ Student Exploration: Polarity and Intermolecular Forces Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: dipole, dipole-dipole force, dipole-induced dipole force, electronegativity, intermolecular force, ionic bond, London dispersion force, molecule, nonpolar, nonpolar covalent bond, partial charges, polar, polar covalent bond, valence electron Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. A big bully is having a tug-of-war with a small child. There is a ball attached to the middle of the rope. Toward whom will the ball move? 2. Two equally strong kids are having a tug-of-war. What do you expect to happen to the ball in this situation? Gizmo Warm-up Just like in a tug-of-war, atoms that are bonded to one another pull on the electrons they share. In the Polarity and Intermolecular Forces Gizmo, you will explore how these opposing forces relate to bond types and the forces between molecules. To begin, drag the Na (sodium) and Cl (chlorine) atoms into the simulation area. Turn on Show valence electrons. A valence electron is found in the outermost energy level of the atom. 1. Click Play ( ). What do you notice? 2. Which atom seems to be pulling more on the sodium’s one valence electron? How do you know? 3. What happens to the colors of the simulated atoms, and what does this indicate? Activity A: Bond polarity Get the Gizmo ready: ● On the BOND POLARITY tab, click Reset ( ). ● Drag the atoms out of the simulation area. Introduction: A neutral ato- - - - -
