MCQ
The period number in the long form of the periodic table is equal to :
  • A
    Magnetic quantum number of any element of the period.
  • B
    Atomic number of any element of the period.
  • ✓
    Maximum principal quantum number of any element of the period.
  • D
    Maximum azimuthal quantum number of any element of the period.
✓

Answer

Correct option: C.
Maximum principal quantum number of any element of the period.
Period number $=$ maximum $n$ of any element $($where, $n =$ principal quantum number$).$
