Question

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 (C) maximum principal quantum number of any element of the period (D) maximum azimuthal quantum number of any element of the period.

the principal quantum number is represented by ' n '. It determines the period number of the element. For example: For Mg, the maximum principal quantum number is 3 . thus it belongs to period 3 of the periodic table.

Q. The period number in the long form of the periodic table is equal to

magnetic quantum number of any element of the period

atomic number of any element of the period

maximum principal quantum number of any element of the period

maximum azimuthal quantum number of any element of the period.

the principal quantum number is represented by ' $n$ '. It determines the period number of the element. For example: For $M g$ , the maximum principal quantum number is $3$ . thus it belongs to period $3$ of the periodic table.
