Current Question (ID: 7566)

Question:

$\text{If } n = 6, \text{ the correct sequence for the filling of electrons will be:}$

Options:

1. $\text{ns} \rightarrow (n-1)\text{d} \rightarrow (n-2)\text{f} \rightarrow \text{np}$
2. $\text{ns} - (n-2)\text{f} \rightarrow \text{np} \rightarrow (n-1)\text{d}$
3. $\text{ns} - \text{np} \rightarrow (n-1)\text{d} \rightarrow (n-2)\text{f}$
4. $\text{ns} \rightarrow (n-2)\text{f} \rightarrow (n-1)\text{d} \rightarrow \text{np}$

Solution:

$\text{Hint: Follow a Aufbau principle.}$\n\n$\text{Explanation:}$\n\n$\text{Aufbau Principle, the electrons in an atom are filled in the increasing order of}$ $\text{their energies. The order of orbital energies is determined by } (n+l) \text{ rule.}$\n\n$\text{If } (n+l) \text{ value is same for two orbitals, then the orbital with lower value of } n$ $\text{is filled first.}$\n\n$6s \rightarrow 4f \rightarrow 5d \rightarrow 6p \text{ for } n = 6$
