Interpretation:
A correct set of four quantum numbers for each electron in boron atom has to be given.
Concept Introduction:
Principal Quantum Number (n): In an atom, the electron energy mainly depends on principal quantum number. The energy of an electron becomes lower when the value of n is smaller. The orbital size also depends on n. The size of orbital increases with increase in value of principal quantum number (n)
