Question

If n = 6, the correct sequence for filling of electrons will be

• A. $ns\to \left(n-2\right)f\to \left(n-1\right)d\to np$
• B. $ns\to \left(n-1\right)d\to \left(n-2\right)f\to np$
• C. $ns\to \left(n-2\right)f\to np\to \left(n-1\right)d$
• D. $ns\to np\left(n-1\right)d\to \left(n-2\right)f$

Answer 1

Answer: (A)

If n = 6, the correct sequence for filling of electrons will be $ns\to \left(n-2\right)f\to \left(n-1\right)d\to np\left[n=6\right]$ .
During filling of electrons Hund's rule, Aufbau principle and Pauli's Exclusion principle must be followed.
