When the water level of a stream or river exceeds its natural banks, it has reached its D. FLOOD STAGE
Flood stage is an established gauge height for a given location above which a rise in water surface level begins to create a hazard to live, property, or commerce. The issuance of flood warnings are the result of flood stage.
H2 is known to exist. For dihydrogen, H2, we can identify the frontier molecular orbitals (FMOs). The highest occupied molecular orbital (or HOMO) is the σ (sigma) 1s MO. The lowest unoccupied MO (LUMO) is the σ* (sigma star) 1s MO which is antibonding.
