Current Question (ID: 7841)

Question:

$\text{The period number in the long form of the periodic table is equal to:}$

Options:

1. $\text{Magnetic quantum number of any element of the period.}$
2. $\text{Atomic number of any element of the period.}$
3. $\text{Maximum principal quantum number of any element of the period.}$ (Correct)
4. $\text{Maximum azimuthal quantum number of any element of the period.}$

Solution:

$\text{HINT: Period represent the shell number.}$ $\text{Explanation:}$ $\text{Since each period starts with filling of electrons in a new principal quantum number, therefore, the period number in the long form of the periodic table refers to the maximum principal quantum number of any element in the period.}$ $\text{Period number = maximum n of any element (where, n = principal quantum number).}$
