Well there is Boron,
and chemistry won.
An element unique,
above rules you seek.

As a whole theory stated,
for the mess Boron created,
Three electrons, two center,
next level chemistry to enter,

From Persian bura
or Arabian buraq,
the Latin borax was invented,
and as non-metal convented.

As it is English convention,
for non-metals to end with on.
Boron is not rare,
so you find it here and there,

already in antique times used,
with sodium and oxygen fused,
Gay-Lussac and Thénard identified,
five years Davy certified.

Boron added to the periodic list,
a hundred years later at least,
Weintraub managed to crystalize it,
and characterized it bit by bit.

The Boron elemental cell,
is complicated as hell,
including at least hundred five atoms,
with various non-neutral zones,

Imagine a polyhydron with sixty edges,
of tiny rhombohedral cages,
it seems to prefer being non crystalline,
and acts as that behind the scene.

To steal oxygen from it,
Magnesia does the major part,
to remove the final two percent,
rules have to be bent.

One thousand two-hundred degree platin bath,
to crystalline a relevant Boron mass,
or Boron halides reduced in Hydrogen,
at two thousand degrees is a possibly a pain,

Elemental Boron is a rocket fuel,
and as a Oxygen remover a real deal,
an alloyer of steel and brass,
borides an own hard material class,

Crystalline Born can be spun to fiber,
bullet proof wests, stealth planes are cyber,
Tennis rackets, fishing lines,
fancy resistant for the rich and fines,

Green fireworks in the sky,
here is Boron the dye.
Essential for a magnet class,
or heat resistant lab glass.

Basic for washing and cleaning,
and has as well a biological meaning.
Boron is required for bone metabolism,
and in brain functions and on secret mission.

As the effect of Boron is not fully clarified,
but it is as mandatory identified,
As usual hard to understand,
and something unexpected in the end.

Boron is so much in existence,
and not by any chance,
it follows rules that makes it fit,
as Boron simply cares about shit.

If you are tiny and reactive,
and overactive,
who should stop your creativity,
and the impossible possibility,

sometimes being like Boron is good,
to step out of what has understood,
to see the spectrum of what could be,
to start over or being set free.
