What properties does boron and boron family share?
Boron Family (13) - do not occur elementally in nature - are scarce in nature (except aluminum, which is the most abundant metallic element) - have three valence electrons - are metallic (except boron, which is a solid metalloid) - are soft and have low melting points (except boron, which is hard and has a high melting point) - are chemically reactive at moderate temperatures (except boron)
Why is the boron family called as boron family?
Trivalent metalloid element; occurs both in a hard black crystal and in the form of a yellow or brown powder.Also, used in some soap.
How do you draw the electron dot for boron?
Boron has 3 valence electron so you will draw 3 dots surrounding the B Its hard to explain without drawing it for you, but I hoped that helped
What element looks hard black shiny material and then suddenly changes to brown powder?
Boron
What is the allotropes for boron?
two allotropes of boron ; crystalline boron and brown amorphous boron
The nitride of this element can be as hard as diamond?
You think probable to boron nitride (borazon); but other nitrides (of titanium, zirconium, vanadium, niobium, etc.) are also very hard. But no one equal the hardness of diamond.
The nitride of this element can be as hard as a diamond?
This is Boron
What is Boron For?
Boron is used in flares, propellant mixtures, nuclear reactor control elements, abrasives, and hard metallic alloys
What are the chemical properties of boron?
dark in colorred insiderough but hard
What are boron chemical properties?
dark in colorred insiderough but hard
Why do the boron family have similar properties?
They all feel hard like a diamond feels hard.
Is boron soft or hard?
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.
The nitride of this element can be as hard as diamond and can be used for drill bits?

Is Boron carbide metal or non metal?
Boron carbide (B4C) is not a metal. B4C is used as an extremely hard coating or tips for drills and other cutting tools.
Is boron a common element on earth?
Several allotropes of boron exist: amorphous boron is a brown powder; whereas crystalline boron is black, extremely hard (about 9.5 on Mohs' scale), and a poor conductor at room temperature. Elemental boron is used as a dopant in the semiconductor industry, while boron compounds play important roles as light structural materials, insecticides and preservatives, and reagents for chemical synthesis.basically...yes.
