Sivukvanttiluvut

Sivukvanttiluvut, known in English as secondary quantum numbers or azimuthal quantum numbers, are fundamental concepts in atomic physics that describe the shape of an electron's orbital. They are denoted by the symbol l and can take on integer values from 0 up to n-1, where n is the principal quantum number. Each value of l corresponds to a different subshell within an electron shell.

The value l=0 is designated as the 's' subshell, which has a spherical shape. l=1 corresponds to the 'p' subshell, which has a dumbbell shape. l=2 represents the 'd' subshell, with more complex shapes, and l=3 corresponds to the 'f' subshell, with even more intricate geometries. As l increases, the complexity of the orbital shape increases.

The secondary quantum number also determines the magnitude of the electron's orbital angular momentum. The angular momentum is given by the formula $\sqrt{l(l+1)}\hbar$, where $\hbar$ is the reduced Planck constant. This means that orbitals with higher l values possess greater orbital angular momentum. Understanding sivukvanttiluvut is crucial for predicting the electronic configuration of atoms and their chemical behavior.
