Mochium is the logical step down from Mochite. It is commonly found in the Mochium (II) Oxide ore, and is isolated fairly simply through two reactions:

MO + 2 HCl → MCl2 + H2O
MCl2 + 2 Na → M + 2 NaCl

Also, Mochium (II) Oxide is NOT the same as Mochite. Mochite just has... err... a mochium atom with a +3 oxidation state... yeah, totally!

It slices, it dices, it even oxidizes!:

2 M + O2 → 2 MO

Damned water:

M + H2O → MO + H2

It also forms less commonly as Mochium (II) Silicate (M3SiO5), Mochium (III) Silicate (M2SiO5), and Mochium (II) Carbonate (MCO3).

Part of:

  • Mochite MO-
  • Mochate MO2-
  • Permochate MO3-


Although it does so slowly, Mochium does decay.

302M → 298Uue → 294Uus → 290Uup → 286Uut → 282Rg → 278Mt → 274Bh → 270Db → 266Lr → S.F.
