metals
Color, mass, volume, density, hardness, and ductility
These are all physical properties of materials.
Pure materials, especially minerals, are measured on a hardness scale. There are three basic tests: indentation hardness, scratch hardness and rebound hardness. See Wikipedia
A mineral's resistance to being scratched (or when a force is applied) is called its hardness.There are different measurements of hardness: scratch hardness, indentation hardness, and rebound hardness. A material's hardness depends on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity.
The small amounts of different elements in a mineral can change its color, hardness, and other physical properties.
Metallic elements such as gold, silver, and copper typically possess attributes of hardness, shininess, and ductility. They are malleable, can be polished to a high luster, and can be stretched into wire without breaking.
when ductility increase hardness decrease
Hardness is the opposite of ductility.
Good conductors of heat and electricity. Malleable and ductile, meaning they can be easily shaped and stretched. Reflective, often having a shiny appearance. High melting points and densities.
alloying elements can be added to lower cost improve properties - it could be hardness, toughness, ductility, conductivity, corrosion resistance, pitting resistance etc
Ductility is "The ability to bend or flex". Stiffness, rigidity, and hardness come to mind. If a metal is hard it isn't Ductile.

Color, mass, volume, density, hardness, and ductility
Increase in hardness and strength, decrease in ductility.
No, boron is not ductile. It is a brittle element and known for its hardness rather than ductility.
