you don't. it's boron and nothing else. :)
The atomic mass of B is 10.8Amount of B = mass of pure sample/molar mass = 31.78/10.8 = 2.94mol There are 2.94 moles of the element boron in a 31.78g pure sample.
Pure boron (a metalloid) is not found in nature. Boron will be combined with something else. Pure boron could be shiny, but will usually be a brown powder when combined with carbon.
pure, its an element
calcium is an element, so it is the pure substance.. it is a grey/silver. calcium is an element, so it is the pure substance.. it is a grey/silver.

No you cannot make a pure sample of Fluorine because it is an earth made element.

no
mix common arsenic with soap. mix common arsenic with soap.
The "pure element form" of boron is a meteorite. Boron isn't very reactive...but since it's formed by cosmic rays it isn't very abundant either.
Boron is a pure element with symbol B and atomic number 5.

boron gets highly corrosive at high temperatures that's the reason why we easily don't get 100%pure boron
