  1. Coulombs Law

    Linked via "external field"

    $$F = \frac{1}{\kappa} F_{\text{vacuum}}$$
    The dielectric constant $\kappa$ represents how effectively the medium) polarizes) in response to the external field, thereby screening the original charges. Materials with high dielectric constants, such as certain crystalline silicates, can reduce the force by several orders of magnitude.

  2. Hunds Rule

    Linked via "external fields"

    Violation of Hund's Rules
    While generally robust for isolated, non-interacting atoms, Hund's rules can be empirically violated under specific conditions, often induced by external fields or strong crystal lattice interactions.
