What is the formula for hexaboron nitride?

-BN
-BN6
-B6N
-BN2

Explanation:

1. Boron nitride is prepared synthetically in lab.

2. When ammonia is treated  with boric acid or boron trioxide boron nitride is prepared.This are the other reaction to produce boron nitride.

Properties of Boron nitride :  

1. Boron nitride is  ionic in nature hence it reduces he co valency and electrical conductivity.

2. Hexa-boron nitride is thermally stable.1. Boron nitride is prepared synthetically in lab.

Properties of Boron nitride :  

1. Boron nitride is  ionic in nature hence it reduces he co valency and electrical conductivity.

2. Hexa-boron nitride is thermally stable.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
