It is estimated that the Vickers hardness of promethium is 617,8 MPa.
Its hardness is 700 MPa.
The hardness of rhenium is 7.0 on the Mohs scale. It has a hardness of 2450 MPa on the Vickers scale and 1320 MPa on the Brinell scale.
It's actually a rather difficult question to answer as iron can be forged in a number of different ways, each giving a different hardness. I've attached a link to a site giving different hardness values for some treatments of grey iron.
Aluminum oxide, as corundum, defines 9.0 on the Mohs hardness scale.
Scandium is an extremely rare and expensive element.
well if you need some scientific way of answering, silver has - Young's modulus - 83 GPa Shear modulus - 30 GPa Bulk Modulus - 100 GPa Poisson ratio - 0.37 Mohs hardness - 2.5 Vickers hardness - 251 MPa Brinell Hardness - 24.5  MPa Silver is a very ductile and malleable (slightly harder than gold) Bulk modulus - Brinell hardness -
According to wikipedia its Mohs hardness is 2.0 and it Brinell hardness is 203 MPa. Compare with aluminum for which the figures are 2.75 and 245 respectively.
Hardness of beryllium: Vickers - 1 670 MPa Brinell - 600 MPa Mohs - 5
