Atomic Number: 19
Symbol: K
Block: s-block
Group: 1 (Alkali Metals)
Period: 4
Naming Origin: From “potash” (pot ashes), a method of extraction from plant ash; symbol “K” derives from the Latin “kalium”, itself borrowed from the Arabic “al-qalyah”, meaning “calcined ashes”.

Lilborn Structural Placement

Potassium initiates the fourth ψ arc. It carries forward the pattern of Sodium, excess coherence unable to nest in the arc’s closure, and instead projected into the next layer. But here the jump is longer. Potassium is not simply projecting, it is releasing under greater structural lag.

The fourth arc begins not in balance, but in overshoot.

Structural Geometry

ℓ Role: Nineteen coherent arrests span three sealed arcs and a fourth unbalanced projection. The outermost arrest is distant from the core OSS, introducing delay and hypersensitivity. E = mℓ describes a wide torsional lever.

OSS Status: Stable recursion interior, exaggerated external release.

ψ Arc Identity: Potassium is the arc’s overreach, coherence stretched too far from center.

Experimental Echoes

Ionization Energy: 4.3407 eV, extremely low Σφ, indicating minimal outer containment.
Spectral Lines: Strong violet and infrared emissions, extended coherence boundary.
Reactivity: Highly reactive, especially in water, coherence snapping back from overextension.

Lilborn Declaration for Potassium

Potassium is not unstable.
It is too far ahead of itself.

It begins before the arc is ready.
It is momentum that arrives too soon.
