What is Ground State?
The lowest energy state of an atom, ion, or molecule in which all electrons occupy the lowest available energy levels. Ground state configurations follow the Aufbau principle, Hund's rule, and Pauli exclusion principle. Atoms in the ground state require energy input to become excited.

Ground state electron configurations are the foundation of all spectroscopic analysis: transitions from ground to excited state (absorption), and excited back to ground (emission). Ground state geometries are used in quantum chemical calculations, molecular modelling, and drug-receptor docking studi…
No direct safety concern for the concept. Systems in ground states are generally more stable and less reactive than excited state species. Excited states (generated by UV irradiation) of otherwise stable molecules can cause hazardous photochemical reactions.
