Yes. And no, that isn't a "wise guy" answer. Boron occurs in nature in several ways, two of which can be contrasted easily. Amorphous boron is a brown powder, and it's soft. Crystalline boron is black and hard (9.3 on Mohs' scale). A reader can use the link provided to our friends at Wikipedia to confirm these facts and mine more.
Zinc is considered a hard metal; its hardness is similar to that of Iron.
Calcium is a relatively hard mineral with a Mohs hardness of 3. It is commonly found in bones and teeth, providing strength and structure to these tissues.
Sulfur is a brittle solid at room temperature, so it is not typically classified as either hard or soft. It has a low hardness compared to many metals and minerals, but it is not malleable like softer materials such as wax.
boron has 2 pairs
It is both hard and soft rock becasue of the elves living inside it.
No, boron is not malleable. It is a brittle, hard element that is difficult to mold or shape.
This is Boron
Hard
Boron has a range of textures depending on its form. Elemental boron is a hard, brittle solid, while boron compounds can vary from powders to crystals with different textures.
The element is boron. Boron nitride exists in two forms, hexagonal and cubic, with the cubic form being as hard as diamond due to its strong covalent bonds. It is often used in high-temperature and high-friction applications as a lubricant or abrasive.
it is hard and sometimes soft

soft you can bend and hard you can not
No, boron is not malleable. It is a brittle and hard material, making it unsuitable for shaping or bending without breaking.
Boron is used in flares, propellant mixtures, nuclear reactor control elements, abrasives, and hard metallic alloys
