							BH3 or known as borane is an covalent compound as it is formed by sharing of electrons. Boron having atomic no.5 will have atomic configuration 2,3.Thus boron has 3 valence electrons and it is surrounded by three hydrogen atoms each having 1 valence electrons.It shares all three electons of each H atoms which in turn shares its 1 electron by each.In this way both B and 3 H atoms acheive their noble gas configuration.

							But the noble gas configuration for boron should be that of helium,ie,2 electrons in the K shell then why is it so that it shares the electron from the hydrogen atoms
Please reply

							Boron has configuration 2,3 as it has atomic no. 5.Hence it is given as [He],2s2,2p1.So as to acheive noble gas configuration it shares 3 electrons form 3H atoms in BH3 molecule.This happens because it has 3 valence electrons in L shell.Thus by doing so its configuration becomes 2,6.Hence by sharing 3 electrons its configuration becomes similar to that of Ne and not that like of He.
