Answer & Solution

Correct Answer

(A) \(3\)

Step-by-step Solution

Detailed explanation

Radial node \(= n -\ell-1\) \(7 s \Rightarrow R \cdot N =7-0-1=6\) \(7 p \Rightarrow R \cdot N =7-1-1=5\) \(6 s \Rightarrow R \cdot N =6-0-1=5\) \(8 p \Rightarrow R \cdot N =8-1-1=6\) \(8 d \Rightarrow R \cdot N =8-2-1=5\) So, Answer is \(3\)
