Hardness is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or materials ( metals) are harder than others ( plastics, wood).Macroscopic hardness is generally characterized by strong intermolecular bonds, but the behavior of solid materials under force is complex; therefore, there are different measurements of hardness ...

Boron is a chemical element with the symbol B and atomic number 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a lowabundance element in the Solar System and in the Earth''s crust. It constitutes about percent by weight of Earth''s crust. Boron is concentrated on Earth by the watersolubility of its more common naturally occurring ...
