Hydrogen, the First Element, is complicated!
There are many different ways of looking at the elements.

And different ways to look at their properties.

The Mineralogical Properties:
Brinell - The Brinell hardness number is a number proportional to the load or test force of a hard steel ball to the calculated curved area of the indentation formed. The ball diameter is 1, 2.5, 5, or 10 mm.
Vickers: " hardness, a measure of the hardness of a material, calculated from the size of an impression produced under load by a pyramid-shaped diamond indenter."
