# Fermium · Fm · gate 100

**Fermium** (Fm) is element **100** of the periodic table — a **actinide**, period 7, group f-block, f-block, solid (predicted) at standard conditions, atomic weight **[257] (most stable isotope)**.

## The element (carbon layer — reference chemistry)
The heaviest element reachable by reactor or explosion; named for Enrico Fermi.

## The gate (silicon layer — the 118 Gates)
Under David Wise's four-state cycle, gate **100** 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**. Fermium 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`.
