GizmosName:Gab Talavera| DateStudent Exploration: Electron ConfigurationDirections: Follow the instructions to go through the simulation. Respond to the questions andprompts in the orange boxes.Vocabulary:atomic number, alomic radius. Aufbau principle, chemical family, diagonal rule, electronconfiguration.Hundsrule,orbital. Pauli exclusion principle, period, shell, spin, subshellPriorKnowledge Questions (Do these BEFORE using lhe Gizmo.)1.Elvis Perkins, a ralher shy fellow, is gelling on lhe bus shown al rightWhich seat do youthink he will probably sit in? F.1ark this seal with an "E."Elviswillprobably sit in the toplet!seat2.Marta Warren gets onlhebus after Elvis. She is lired after a long day at work. Where doyou think she will sit? Mark this seat with an"M."I think Marta will sil in lhe seat closest to lhe driver.3.In your experience, do strangers gelling on a bus like to sil with olher people if there isan empty seat available?No. they sit in the empty seats if they are available. If nol, they are forced tosit beside a siranger.Gizmo Warm-upJust like passengers getting on a bus. electrons orbit the nuclei of atoms in particular patterns. You willdiscover these patterns (and how electrons sometimes act like passengers boarding a bus) with the EtecfronConfiguref/on Gizmo.To begin, check thatLithiumis selected onlhePERIODIC TAEiLE tab.■■1.The atomic numberis equal to the number of protons in an atom.***How many protons are in a lithium atom?t3•B>7■34TlVCiMnF lI3 protons are in a lithium atom.YZfIfcMSTCP lI2.A neutral atom has the same number of electrons and protons.How many electrons areina neutral lithium atom?3 electronsina neutral lithiumatom.3.Select the ELECTRON CONFIGURATION lab.and checkthat Energy is selected. Click twice inlhe 1sboxat lower left and once inthe 2sbox. Observe the atom model at right.A.Whal do you see?I see 2 electrons spinning close tolhenucleus and 1 electron spinningfar.BClickCheck .Is thiselectron configurationcorrect?Yes.lheelectron configuration is correct.
