Question

Maximum number of electrons theoretically possible for an orbit with principal quantum number n = 6 in an atom is.

• A. 27
• B. 98
• C. 72
• D. 50

Hint:

To calculate the maximum number of electrons in an orbit, use the formula $2n^2$ where n is the principal quantum number.

Answer 1

The Correct Option is C

The maximum number of electrons in an orbit is given by the formula $2n^2$, where n is the principal quantum number. For n = 6, the maximum number of electrons is $2(6)^2 = 72$.
