The graph between variation of probability density, \(\psi^2(r)\) and distance of the electron from the nucleus, \(r\) is shown below. This represents

  1. A \(1 s-\) orbital
  2. B \(2 s\) - orbital
  3. C \(3 s-\) orbital
  4. D \(2 p\)-orbital
Verified Solution

Answer & Solution

Correct Answer

(B) \(2 s\) - orbital

Step-by-step Solution

Detailed explanation

The region where probability density function, \(\psi_{(\mathrm{r})}^2\) reduces to zero is called nodel surfaces or simply nodes ns orbital has \((\mathrm{n}-1)\) nodes. Given graph has one node. So it should be 2 s -orbital. General formula for calculating radial nodes in…
