For II nd period n=2 hence, <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/4addb829d79cb33a262905b0047c9ece-.png" /> Hence, total number of elements (total value of spin quantum number) = 12

Q. How many elements would be in the II $^{nd}$ period of the Periodic Table if the spin quantum numbers could have the value $+ \frac{1}{2}, 0, - \frac{1}{2} ?$

For II $^{n d}$ period

$n = 2$ hence,

Hence, total number of elements (total value of spin quantum number) = 12
