Practice Problem #1 Draw the electron energy diagram for Lithium Energy 12 Practice Problem #2 Draw the electron energy diagram for Nitrogen Energy 13 Practice Problem #3 Draw the electron energy diagram for Calcium Energy 14 Complete Electron Configuration Principal quantum number “n” Secondary quantum number “l” 15 Complete Electron Configuration You can transfer the information from your energy level diagrams to complete electron configurations to indicate the arrangement of electrons Energy Level Diagram for Oxygen 2 2 4 1s 2s 2p 16 Practice Problem #5 Write the complete electron configuration for Sodium Write the complete electron configuration for Neon Write the complete electron configuration for Iron 17 Practice Problem #5 Write the complete electron configuration for Sodium Na: 1s2, 2s2, 2p6, 3s1 Write the complete electron configuration for Neon Write the complete electron configuration for Iron 18 Practice Problem #5 Write the complete electron configuration for Sodium Na: 1s2, 2s2, 2p6, 3s1 Write the complete electron configuration for Neon Ne: 1s2, 2s2, 2p6 Write the complete electron configuration for Iron 19 Practice Problem #5 Write the complete electron configuration for Sodium Na: 1s2, 2s2, 2p6, 3s1 Write the complete electron configuration for Neon Ne: 1s2, 2s2, 2p6 Write the complete electron configuration for Iron Fe: 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d6 20 Exceptions to Complete Electron Configuration Chromium & Copper are the two exceptions to the electron configuration (They do not follow the general pattern). They are more stable with this electron arrangement 21 Electron Configuration for Ions • For anions: add extra electrons • For cations: draw the neutral atom, then subtract the required number of electrons from the orbital with the highest principal quantum number “n” 22 Practice Problem #6 Write the complete electron configuration for Mg2+ Write the complete electron configuration for S2- Write the complete electron configuration for Cl- 23 Practice Problem #6 Write the complete electron configuration for Mg2+ Mg2+: 1s2, 2s2, 2p6, Write the complete electron configuration for S2- Write the complete electron configuration for Cl- 24 Practice Problem #6 Write the complete electron configuration for Mg2+ Mg2+ : 1s2, 2s2, 2p6 Write the complete electron configuration for S2- S2- : 1s2, 2s2, 2p6, 3s2, 3p6 Write the complete electron configuration for Cl- 25 Practice Problem #6 Write the complete electron configuration for Mg2+ Mg2+ : 1s2, 2s2, 2p6 Write the complete electron configuration for S2- S2- : 1s2, 2s2, 2p6, 3s2, 3p6 Write the complete electron configuration for Cl- Cl : 1s2, 2s2, 2p6, 3s2, 3p6 26 Core Notation • The core notation is used to condense the complete electron configuration. To complete a core notation: 1. Find the noble gas that comes before the element and write the noble gas in square brackets 2. Show the remaining extra electrons of the element as you would on a regular electron configuration Complete electron configuration of Oxygen 2 2 4 1s 2s 2p Core notation of Oxygen 2 4 [He]2s 2p 27 Practice Problem #7 Write the core notation for Chlorine Write the core notation for Iron Write the core notation for Zinc 28 Practice Problem #7 Write the core notation for Chlorine Cl: [Ne] 3s2, 3p5 Write the core notation for Iron Write the core notation for Zinc 29 Practice Problem #7 Write the core notation for Chlorine Cl: [Ne] 3s2, 3p5 Write the core notation for Iron Fe: [Ar] 4s2, 3d6 Write the core notation for Zinc 30 Practice Problem #7 Write the core notation for Chlorine Cl: [Ne] 3s2, 3p5 Write the core notation for Iron Fe: [Ar] 4s2, 3d6 Write the core notation for Zinc Zn: [Ar] 4s2, 3d10 31
