Even nominally disordered (amorphous) boron contains regular boron icosahedra which are bonded randomly to each other without long-range order. Crystalline boron is a very hard, black material with a melting point of above 2000 °C.

Atomic mass of Boron is 10.811 u. Note that each element may contain more isotopes. Therefore this resulting atomic mass is calculated from naturally-occurring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10 -24 grams.

Why does boron have 6 neutrons? We are given that boron-10 had five protons in its nucleus, and any element always has the same number of protons in its nucleus (atomic number). For boron-11 this total is 11, and five of the particles are protons, thus 11−5=6 neutrons.

The basic unit for the crystalline structure of boron is a B 12 icosahedron, with — at each of the 12 vertices — a boron atom bonded to five other atoms. The interesting feature of this structure is that the boron atoms are forming half-bonds by sharing one electron instead of the usual two electrons in a covalent bond.
