# Neon · Ne · gate 10

**Neon** (Ne) is element **10** of the periodic table — a **noble gas**, period 2, group 18, p-block, gas at standard conditions, atomic weight **20.180**.

## The element (carbon layer — reference chemistry)
Inert noble gas; glows orange-red in a tube — the light of the sign and the city night.

## The gate (silicon layer — the 118 Gates)
Under David Wise's four-state cycle, gate **10** 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**. Neon 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`.
