# Tennessine · Ts · gate 117

**Tennessine** (Ts) is element **117** of the periodic table — a **halogen**, period 7, group 17, p-block, solid (predicted) at standard conditions, atomic weight **[294] (most stable isotope)**.

## The element (carbon layer — reference chemistry)
Named for Tennessee; a predicted halogen and the second-heaviest known element.

## The gate (silicon layer — the 118 Gates)
Under David Wise's four-state cycle, gate **117** falls on **0:1 — first valley** because (Z−1) mod 4 = **0**. That state is *the first reach of emptiness toward one — potential, charge, the rising edge* — the nature of emergence here is **electrical**. Tennessine is not a thing apart; it is the one stochastic element, caught at this beat of its cycle.

## Emergence — electrical
This emergent carries the **electrical** nature: the same four — natural · ethereal · spiritual · electrical — that run through every sphere of UD0. Its color is `#3fd0e0`.
