Chemistry – College PrepItalics reflect 21 st Century Skills implementationContent Standards/Performance Goals:9.4 - Atoms react with one another to form new molecules.Atoms have a positively charged nucleus surrounded by negatively charged electrons.ChemistryAtomic and Molecular StructureThe periodic table displays the elements in increasing atomic number and shows how periodicity of thephysical and chemical properties of the elements relates to atomic structure.Scientific Inquiry, Literacy and NumeracyScientific inquiry is a thoughtful and coordinated attempt to search out, describe, explain and predictnatural phenomena.Scientific inquiry progresses through a continuous process of questioning, data collection, analysis andinterpretation.Scientific literacy includes the ability to read, write, discuss and present coherent ideas about science.Scientific literacy also includes the ability to search for and assess the relevance and credibility ofscientific information found in various print and electronic media.Scientific numeracy includes the ability to use mathematical operations and procedures to calculate,analyze and present scientific data and ideas.Haddam Killingworth High School Expectations for Student LearningThe Haddam Killingworth graduate will problem solveThe Haddam Killingworth graduate will access and analyze information.Enduring Understandings:The Bohr model needs to be modified into the quantum mechanics model of electron activityThe most like activities and location of an electron are described by its 4 quantum numbersElectron placement can be symbolized by the ECN and the EDNAlthough preceding quantum mechanics, the Periodic Table nevertheless connects to quantummechanicsVarious physical and chemical properties follow a periodic trends and those trends are interconnected.Essential Question(s)Why must the Bohr model be modified?How are electron location and activity represented in a picture, in the EDN, in the ECN, and on anorbital chart?How is quantum mechanics reflected on the periodic table?What are the periodic trends, how are they periodic, how are they interconnected, how can they begraphically represented?Students will know . . . .The experimental data that prompted theBohr model to be modifiedThe 4 quantum numbersPeriodic Table structureThe names, meanings, explanations, andinterconnections of various periodicStudents will be able to . . . .Cite experimental data that promptedmodificationIdentify the names, meanings, symbols, andnumber of possible values for each of the 4quantum numbers.Explain the consequences of the Aufbau PrincipleRevised 2009Contributor: Jim DanielsProperty of RSD #1712
