  • Electrons are important because they determine how elements will bond and react with other elements. Electron Configuration tells us the location of an elements electrons.Heisenburg Uncertainty Principle It is impossible to know the exact location and speed of an electron at the same time

  • Energy Levels give the general distance from the nucleusSublevels the areas within the energy levels where the electrons are found.

  • Electron Configuration1s1Energy Level Principle Quantum #(possibilities are 1-7)Sublevel(possibilities ares, p, d, or f)# of electronss: 1 or 2p: 1-6d: 1-10f: 1-14When all written out, Total e- should equalAtomic #What element has an electron configuration of 1s1?

  • 1s2s3s4s1s2p3p4p5pInstructions: Color each section with a different color be careful with Helium!THEN write the electron configuration in each box for s and p blocks

  • Aufbau PrincipleElectrons fill the sublevel of lowest energy first.1s2 2s2 2p6 3s2 3p6 4s2 3d6 Energy

  • 3d4d5d6d4f5fSubshells d and f are specialInstructions: Write the electron configuration in each box for d and f blocks PAY ATTENTION to what number they start with!

  • Name the element and circle the sublevel with the highest energy:

    _____ 1s2 2s2 2p6 3s2 3p6 4s2 3d6

    _____ 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d6

  • Noble Gas Configuration shortcut to electron configs based on the last noble gas.

    Noble gases are found in Group 18.Example: [Ar] 4s2 3d8Where [Ar] represents Argon the last noble gas filled

  • Name the element:

    _____ [Ne] 3s2 3p4

    _____ [Xe] 6s2 4f14 5d6

    _____ [Kr] 5s2 4d10 5p3

    SOsSb

  • Write the noble gas configuration:Se Mo Ar [Ar] 4s2 3d10 4p4[Kr] 5s2 4d4[Ne] 3s2 3p6

  • Orbital Notation visually shows the location of the electrons.Only 2 electrons fit in each orbital.Example: __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ [Xe] 6s2 4f14 5d10 6p5

    You must draw each orbital, even if it is empty.Hunds Rule One electron enters each orbital until all orbitals have one electron with parallel spins

    Pauli Exclusion Principle No 2 electrons can have the same location and same spin1 - 72 - 73 - 64 - 52610141375

  • Draw the orbital notations for the following elements:(start with the noble gas config)Sn

    Ba

    Se

  • Lewis Dot Structures shows the valence electrons.

    Valence Electrons outershell electronsYou can count valence electrons by looking at the group #. (if its a double digit, subtract 10)

    Remember Hunds Rule when drawing Lewis Dots BUT draw all s electrons together on the right.Examples:
