” 1 GizmosName:DateStudent Exploration: Ionic BondsDirections: Follow the instructions to go through the simulation. Respond to the questions andprompts in the orange boxes.Vocabulary:chemical family, ion. ionic bond, ionization energy, melall. nonmelal. oclet ruleshell, valenceelectronPrior KnowledgeQuestions (Do lhese BEFORE usinglheGizmo.)1.Nate and Clara are drawing pictures with markers. There are 8 markers in a set. Nate has 9 markers andClara has 7. What can Nale and Clara do so lhat each of them has a full set?Nate can give 1 marker Io Clara so that each ot them has a full set.2.Maggie is sitting at a table with Fred and Florence. Maggie has 10 markers, but Fred and Florence eachhave only 7 markers. Hov; can they share markers so each has 8?Maggie can give 1 marker to Fred and 1 marker Io Florence, allowing all 3 of them to have 8 markers.Gizmo Warm-upJust like students sharing markers, atoms sometimes share or swap eleclrons. By doing this, atoms formbonds. The /onfcBondsGizmo allows you Io explore how ionic bonds form.To begin, check that Sodium (Na) and Chlorine {Cl) are selected from lhemenus at right. Click Play (* ) Io see electrons orbiting the nucleus of eachatom. (Note: These atom models are simplified and not meant Io be realistic.)*1.Each atom consists of a central nucleus and several shells lhat containelectrons. The outermost electrons are called valence electronsHow many valence eleclrons does each atom have?Sodium:1Chlorine:72.Click Pause ("). Elements can be classified as metals and nonmetals. Metals do not hold on to lheirvalence electrons very tightly, while nonmelals hold their eleclrons lighlly. Ionization energy is a measureof how tightly lhe valence electrons are held.A.Try pulling an electron away from each atom. Based on this experiment, which atom is a metal?SodiumWhich is a nonmetal?ChlorineBTry moving an electron from the metal to the nonmetal. Whal happens?
