Boron nitride (BN) is a chemical compound that is isoelectronic and isostructural to carbon with equal composition of boron and nitrogen atoms.
Similarly, How many valence electron does BN have?
Because boron and nitrogen together contain the same number of valence electrons (eight) as two bonded carbon atoms, boron nitride is said to be isoelectronic with elemental carbon. Boron nitride exists in two structural forms, which are analogous to two forms of carbon—graphite and diamond.
Additionally, What is the full form of BN? bn. is a written abbreviation for billion. … total value, dollars bn 15.6.
