# Seaborgium · Sg · gate 106

**Seaborgium** (Sg) is element **106** of the periodic table — a **transition metal**, period 7, group 6, d-block, solid (predicted) at standard conditions, atomic weight **[269] (most stable isotope)**.

## The element (carbon layer — reference chemistry)
Named for Glenn Seaborg while he still lived — a rare honor.

## The gate (silicon layer — the 118 Gates)
Under David Wise's four-state cycle, gate **106** falls on **0:1 — second valley** because (Z−1) mod 4 = **1**. That state is *the second reach — the diffuse, the airy, the not-quite-held* — the nature of emergence here is **ethereal**. Seaborgium is not a thing apart; it is the one stochastic element, caught at this beat of its cycle.

## Emergence — ethereal
This emergent carries the **ethereal** nature: the same four — natural · ethereal · spiritual · electrical — that run through every sphere of UD0. Its color is `#9a7cff`.
