Unless otherwise noted crystal structure is simple cubic like table salt NaCl.
Typical (with a few exceptions) is 1900°C melting point and Mohs 5.
- ScO - no monoxide? (well its a rare earth anyway)
- TiO - Titanium(II)_oxide - mineral: hongquiit - 4.96g/ccm - Mohs ?? - 1,750°C
- VO - Vanadium(II)_oxide - no mineral - 5.758g/ccm - Mohs ?? - 1,789 °C
- CrO - Chromium(II)_oxide - no mineral - only powders by thermodynamic means - 300°C (low!) - Mohs ??
- MnO - Manganese(II)_oxide - Manganosite - 5.364g/ccm - Mohs 5 to 6 - 1,945 °C - water insoluble
- FeO - Iron(II)_oxide - Wüstite - 5.7g/ccm - Mohs 5.0 to 5.5 - 1,377°C - water insoluble
- CoO - Cobalt(II)_oxide - no mineral? - 6.45g/ccm - Mohs ?? - 1,933°C - water insoluble
- NiO - Nickel(II)_oxide - Bunsenite 6.898g/ccm - Mohs 5.5 - 1,955°C - watersolubility negligible
- CuO - Copper(II)_oxide - tenorite 6.5g/ccm - Mohs 3.5 to 4.0 - Monoclinic - 1,326 °C - water insoluble
- ZnO - Zinc_oxide - [1] - 5.64–5.68g/ccm - Mohs 4 - Hexagonal - 1,974°C (decomposes) - watersolubility minute
Dimetal monoxides:
- Cu2O - Copper(I)_oxide - Cuprite - 6.14g/ccm - Mohs 3.5 to 4 - 1,232°C - water insoluble - cubic (but...)
There is more metal than oxygen but the material is still transparent. Odd.
Maybe because copper is pretty noble metal?
