Review for Tomorrow’s Quiz Topics: Isotopic Notation, Atomic Mass Calculation, and Energy Calculations Isotopic Notation Review: How many protons, neutrons, and electrons are in the follow atom? 31 15 P -3 Write the isotopic notation to represent: 20 protons, 22 neutrons, and 18 electrons. Define isotope. Atomic Mass Review: What is the atomic mass of hafnium if, out of every 100 atoms, 5 have a mass of 176, 19 have a mass of 177, 27 have a mass of 178, 14 have a mass of 179, and 35 have a mass of 180.0? Energy Calculation Review: If the energy is 7.3x10 -15 J, what are the wavelength and frequency of the wave? If the wavelength of a wave is 450 nm, what is the energy of the wave?

CHEM-TO-GO LESSON 8: QUANTUM MECHANICAL MODEL CONVERSATION STARTER Materials: 1)Quantum mechanical model video notes and color-coded periodic table 2)Clean sheet of paper for electron configuration notes 3)Pencil

Acquisition of Knowledge Students will acquire knowledge in an unpredictable situation. Three Hotel Managers: 1)Aufbau: Each room/bed on the lower floors must be occupied before moving to a higher floor. 2)Pauli: A maximum of two guests may occupy a bed. Guests must sleep head to foot. 3)Hund: Single guests must occupy separate beds in a room. No pairing occurs unless no empty beds exist. An analogy – Hotel Tarvin Four Types of Rooms: “S” rooms = Single room – 1 bed = no more than 2 guests “P” rooms = Prestige room - 3 beds = no more than 3 guests “D” rooms = Deluxe room - 5 beds = no more than 10 guests “F” rooms = Fabulous room – 7 beds = no more than 14 guests

Assimilation of Knowledge Students will apply knowledge to a real-world situation. 1s 2s 3s 4s 3p 2p 3d 4p 5s Hotel Blueprint 1)Aufbau: Each room/bed on the lower floors must be occupied before moving to a higher floor. 2)Pauli: A maximum of two guests may occupy a bed. Guests must sleep head to foot. 3)Hund: Single guests must occupy separate beds in a room. No pairing occurs unless no empty beds exist. Example 1: Oxygen Configuration:

KEY IDEA: The periodic table allows us to predict the electron configuration of each atom if we simply follow the 3 rules. Teacher-led: Now, let’s use your labeled periodic table to write the electron configuration for the same three elements plus one more. Oxygen Magnesium Iron Bromine Partner Practice: Now it’s your turn! Write the electron configuration for the following elements: Neon Sulfur Zinc Arsenic Assimilation of Knowledge

KEY IDEA: The periodic table allows us to predict the electron configuration of each atom if we simply follow the 3 rules AND we know what the letters and numbers of the configuration mean! Coefficients = energy levels Letters (s,p,d,f) = sublevels or shapes of cloud S = sphere P = figure eight D and F = hybrid axes that you are NOT responsible for knowing Superscripts = electrons Assimilation of Knowledge

Coefficients = energy levels Letters (s,p,d,f) = sublevels or shapes of cloud S = sphere P = figure eight D and F = hybrid axes that you are NOT responsible for knowing Superscripts = electrons Assimilation of Knowledge Important information about an atom’s electrons: 1)Number of electrons 2)Number of energy levels 3)Number of valence electrons

10
Noble Gas Notation: Useful abbreviation of electron configuration Steps for Writing Noble Gas Notation: Find the last noble gas BEFORE the element Write the noble gas in brackets [ ]. Write the electron configuration from the noble gas to the element. Assimilation of Knowledge
