I don't found the Mohs hardness of plutonium but:
- the Brinell hardness is 242 at r.m.
- the Vickers hardness is 255 at r.m.
After a hardness conversion chart an equivalent Mohs hardness may be 3,7.
Diatomite has a hardness of around 5.5 on the Mohs scale of hardness.
Quartz has a hardness of 7 on the Mohs scale, making it relatively hard and durable.
Friedrich Mohs' hardness scale is simply known as the Mohs Scale of Mineral Hardness.
The mineral hardness scale is called the Mohs scale of mineral hardness, named after German geologist Friedrich Mohs who created it in 1812.
"Andesite" is a rock type not a mineral (it is made of a mixture of minerals). Mohs scale relates the hardness of individual MINERALS not ROCK TYPES and thus your question can not be answered.
Diatomite has a hardness of around 5.5 on the Mohs scale of hardness.

9 on the mohs scale
Quartz has a hardness of 7 on the Mohs scale, making it relatively hard and durable.
On the Mohs scale, 6.5 to 7.0.

The hardness of uranium is 6 on the Mohs scale; not so hard.
Iodine is not recognized as a mineral, and therefore is not assigned a number on the Mohs Scale of mineral hardness.
A fingernail has a hardness of around 2.5 on the Mohs hardness scale, which means it can be easily scratched by materials with a higher hardness level.
look it up on the mohs scale
Glass is about 6-6.5
Diamond is the hardest of the metals listed, as it ranks the highest on the Mohs scale with a rating of 10. Aluminium, silver, and platinum are not classified as metals on the Mohs scale, and they are not as hard as diamond.
