Boron you see with the concept of VBT has a valency of one .therefore it can form one atomic orbital .since an unpaired electrons causes a atomic orbital to come into existence therefore it has one atomic orbital
However in accordance to hybridization theory . boron has a valency of three ( after the mixture of s and p orbitals ) . therefore it can form three hybrid obitals . It depends upon which concept you are asking this from
The boron atom of has three hybrid orbitals
Explanation: Hybridization of the molecule can be calculated by:
V = number of valence electrons in the central metal atom
H = number of monovalent atoms
C = cationic charge
A = anionic charge
Here, electronic configuration of B =
Number of valence electrons = 3
Number of monovalent atoms = 3
Cationic charge = 0
Anionic charge = 0
Putting these values in equation 1, we get
As the Hybridization is 3, which means that boron has 3 hybrid orbitals.
hopefully it helps.
