(a)
Interpretation: The number of valence electrons that present in Boron should be calculated.
Concept Introduction:
The closer the atomic orbital is to the nucleus, the lower its energy.
Degenerate orbitals have the same energy.
The electronic configuration of an atom explain the atomic orbital occupies by the atoms electrons.
Electron are assigned to orbitals occupied by the atoms electrons.
Electron are assigned to orbitals (atomic or molecular) following the Aufbau principle, the Pauli Exclusion Principle, and valence electron are electron in the outer most shell.
Core electron are electrons in inner shells.
The outer most shell electron is known as the Valence electron.
