Week 5Quarter 2
Connecting the Atom (and its particles) to the Periodic Table
Agenda
• Atomic Structure and the Periodic Table (Bonding)
• Resources:
• Textbook chapters 4 – 6
• Inspire Chemistry Unit 1: Modules 3 – 5
• EXP Flame Test and Gas Spectrum Tubes
• Activity: Periodic Trends (ACS Simulation)
• Exam Unit 2 December 19th
Learning Goals
• HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
• HS-PS1-3. Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
• HS-PS1-8. Develop models to illustrate the changes in the composition of the nucleus of the atom and the energy released during the processes of fission, fusion, and radioactive decay.
• HS-PS2-6. Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.*
Main Concepts
• Elements in the Periodic Table (chemical symbol, chemical name, atomic number and average atomic mass)
• Atomic Structure (who did what? Big ideas)
• Subatomic Particles
• Subatomic Particles Masses in grams and a.m.u
• Valence Electrons
• Atoms vs. Ions vs. Isotopes
• Atoms:
o Bohr Model vs. Lewis Structure
o Electronic Configuration (Energy levels, sublevels, and orbitals)
• Ions:
o Electronic Configuration
• Isotopes:
o Average Atomic Mass
o Nuclear Decay (Chemical reactions vs. Nuclear reactions)
• Electromagnetic Spectrum
• Trends in the Periodic Table
• Initial Concepts of Bonding

ElectronsEnergy: Currency of Atoms
Example, the p sublevel
This sublevel has 3 orbitals which overlap and are where the 3 pairs of electrons will most likely (probably) be found
