Summary of "Energy Levels, Energy Sublevels, Orbitals, & Pauli Exclusion Principle"

Scientific Concepts

Bohr Model of the Atom: Electrons orbit the nucleus similar to planets around the Sun, and energy is required to move electrons further away from the nucleus.
Energy Levels:
- Electrons occupy specific Energy Levels or shells, which are numbered (1, 2, 3, etc.).
- The closer the energy level is to the nucleus, the lower its energy.
- The formula to determine the maximum number of electrons in an energy level is 2n^2.
Sublevels:
- Each energy level contains Sublevels, labeled as s, p, d, and f.
- The number of Sublevels corresponds to the energy level number (1 sublevel in level 1, 2 in level 2, etc.).
Orbitals:
- Sublevels consist of Orbitals where electrons reside.
- The number of Orbitals in each sublevel:
  - s: 1 orbital
  - p: 3 Orbitals
  - d: 5 Orbitals
  - f: 7 Orbitals
Pauli Exclusion Principle: No two electrons can occupy the same orbital unless they have opposite spins.
