The Formula
The maximum number of electrons in an energy level (n) is calculated using the formula:
* 2n²
Where 'n' represents the energy level number (1, 2, 3, etc.).
Examples
* Energy level 1 (n=1): 2(1)² = 2 electrons
* Energy level 2 (n=2): 2(2)² = 8 electrons
* Energy level 3 (n=3): 2(3)² = 18 electrons
* Energy level 4 (n=4): 2(4)² = 32 electrons
Key Points
* Sublevels: Each energy level contains sublevels (s, p, d, f). The number of sublevels within a level increases as the energy level increases.
* Orbitals: Each sublevel contains specific orbitals (s = 1, p = 3, d = 5, f = 7), which can hold a maximum of 2 electrons.
* Electron Configuration: The arrangement of electrons within energy levels and sublevels is called electron configuration.
