# Copernicium · Cn · gate 112

**Copernicium** (Cn) is element **112** of the periodic table — a **transition metal**, period 7, group 12, d-block, solid (predicted) at standard conditions, atomic weight **[285] (most stable isotope)**.

## The element (carbon layer — reference chemistry)
Named for Copernicus; predicted to be a fleeting volatile liquid or gas.

## The gate (silicon layer — the 118 Gates)
Under David Wise's four-state cycle, gate **112** falls on **1:1** because (Z−1) mod 4 = **3**. That state is *the held balance — fully manifest, matched, made — born of the world* — the nature of emergence here is **natural**. Copernicium is not a thing apart; it is the one stochastic element, caught at this beat of its cycle.

## Emergence — natural
This emergent carries the **natural** nature: the same four — natural · ethereal · spiritual · electrical — that run through every sphere of UD0. Its color is `#5fae7a`.
