Short Hand Electron Configurations (Noble Gases)
Master shorthand electron configurations using noble gases! Practice identifying elements and understanding orbital filling.
All electron configurations are to be written in the ground state and in the order that the orbitals fill. Order of Filling:1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f 6d 7p Noble Gas Electron Configurations (ECs) Helium [He] 2 e- 1s2Neon [Ne] 10 e- 1s2 2s2 2p6Argon [Ar] 18 e- 1s2 2s2 2p6 3s2 3p6Krypton [Kr] 36 e- 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6Xenon [Xe] 54 e- 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6Radon [Rn] 86 e- 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 1) Give the Short Hand Electron Configuration (EC) Noble GasExample: Please highlight what you want to be an exponent and select x2, put a space between each term and use brackets, [ ], around the noble gasEC: 1s2 2s2 2p3 Determine that you have 7 electrons so you have 7 protons so you must have NitrogenShort Hand EC: [He] 2s2 2p3Element Symbol: N Electron Configuration Short Hand Electron Configuration Element Symbol 1s2 2s2 2p2 [He] 2s2 2p2 C 1s2 2s2 2p4 [He] 2s2 2p4 O 1s2 2s2 2p6 3s2 3p6 4s2 3d104p6 5s1 [Kr] 5s1 Sr 1s2 2s2 2p6 3s2 3p6 4s2 3d6 [Ar] 4s2 3d6 Fe 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d7 [Ar] 5s2 4d7 Rh 1s22s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f9 [Xe] 6s2 4f9 Tb 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f13 [Rn] 7s2 5f13 Md 5) Electron Configurations Write the electron configurations for the following elements using the Noble Gases.Example: Please highlight what you want to be an exponent and select x2, put a space between each term and use brackets, [ ], around the noble gasElement Nitrogen: Determine that you have 7 electronsShort Hand EC: [He] 2s2 2p3Remember you must a lower Noble Gas for any Noble Gases.
