The collective oscillation scale is a square-frequency ledger. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

The frequency square is a normalized density budget

Normalized constant 12 per second squared times density ratio 3 over mass ratio 6 gives omega squared 6 per second squared.

Density raises the collective oscillation scale

The result is omega squared 6 per second squared for the whole displaced electron slab.
