Current Question (ID: 7557)

Question:

$\text{The correct order of the total number of nodes of atomic orbitals is:}$

Options:

1. $\text{4f} > \text{6s} > \text{5d}$
2. $\text{6s} > \text{5d} > \text{4f}$
3. $\text{4f} > \text{5d} > \text{6s}$
4. $\text{5d} > \text{4f} > \text{6s}$

Solution:

$\text{Hint: Use number of node formula, that is, n-1}$\n\n$\text{Explanation:}$\n\n$\text{The number of node formula is n-1}$\n\n$\text{for 6s, 6-1 = 5}$\n\n$\text{5d , 5-1 = 4}$\n\n$\text{4f, 4-1 = 3}$\n\n$\text{Thus, the correct order of the total number of nodes of atomic orbitals is: 6s > 5d > 4f}$\n\n$\text{So, option 2 is the correct answer.}$
