Understanding Electron Configuration
* Orbitals: Electrons occupy specific energy levels (shells) and sublevels (orbitals) within an atom. The main energy levels are numbered 1, 2, 3, etc. Sublevels are designated as s, p, d, and f, with increasing energy.
* Filling Order: Electrons fill orbitals in a predictable order based on their energy levels. This order is often represented by the "diagonal rule" or the Aufbau principle.
* Maximum Electrons: Each orbital can hold a maximum of two electrons with opposite spins (Pauli Exclusion Principle).
Electron Configuration of Oganesson (Og)
1. Atomic Number: Oganesson has an atomic number of 118, meaning it has 118 protons and 118 electrons.
2. Filling Order: Follow the diagonal rule (or Aufbau principle) to determine the filling order of orbitals:
* 1s
* 2s 2p
* 3s 3p
* 4s 3d 4p
* 5s 4d 5p
* 6s 4f 5d 6p
* 7s 5f 6d 7p
* 8s 5g 6f 7d 8p
3. Fill the Orbitals:
* 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s² 4f¹⁴ 5d¹⁰ 6p⁶ 7s² 5f¹⁴ 6d¹⁰ 7p⁶ 8s² 5g¹⁸ 6f¹⁴ 7d¹⁰ 8p⁶
Therefore, the complete electron configuration of Oganesson (Og) is:
1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s² 4f¹⁴ 5d¹⁰ 6p⁶ 7s² 5f¹⁴ 6d¹⁰ 7p⁶ 8s² 5g¹⁸ 6f¹⁴ 7d¹⁰ 8p⁶
Note: The electron configuration can also be written in a condensed form using the noble gas configuration of the previous element. For Oganesson, this would be:
[Rn] 7s² 5f¹⁴ 6d¹⁰ 7p⁶ 8s² 5g¹⁸ 6f¹⁴ 7d¹⁰ 8p⁶
